latest crash log

Added latest log from a crash, interestingly, after connecting over ssh to machine, it rebooted itself, also discovbered that UnBlank LockScreen gnome-shell extension (https://extensions.gnome.org/extension/1414/unblank/) is preventing this to be happening.

From the last log:

There are more crashes, but this is the first one.

7.0.2 monitors connected through HDMI

After conecting monitors through HDMIs (one directly to laptop one through dock) instead of DPs (both from dock) it is even worst, as at some point, it stopped recognizing one screen completely, before it even crashed.

Want to give https://koji.fedoraproject.org/koji/taskinfo?taskID=145136493 a try for me and see if it resolves the issue?

Let me test today the behaviour on 7.0.3-200.fc44.x86_64

So, same freeze on 7.0.3-200.fc44.x86_64, only working workaround for this is to enable https://extensions.gnome.org/extension/1414/unblank/

Just to clarify, did you test specifically with the build that I linked above, or the regular koji build of 7.0.3? They are not the same

with  https://koji.fedoraproject.org/koji/taskinfo?taskID=145136493 after lock screen, and unlocking after ~30 minutes, external screens are working, internal is black.

I am experiencing the same issue on a ThinkPad P1 Gen 7 (same hw to original reporter). I am using the laptop standalone with no external monitor connected.

The system fails to wake up after being suspended for a long period. Specifically, it wakes up fine after 18 minutes, but fails to wake up after being suspended for one hour.

uname -a
Linux fedora 7.0.3-200.fc44.x86_64 #1 SMP PREEMPT_DYNAMIC Thu Apr 30 14:08:57 UTC 2026 x86_64 GNU/Linux

kernel is from "normal" repo. Will try https://bugzilla.redhat.com/show_bug.cgi?id=2463170#c6 later

After aplying your kernel, and downgrading linux-firmware the behavious is like this (hopefully helpful):

```

**Critical Hardware State Mismatch:**
- **Expected pixel_rate:** 154130 Hz (normal full-resolution operation)
- **Actual pixel_rate:** 38971 Hz (~25% of expected value)
- **Expected port_clock:** 243000 kHz
- **Actual port_clock:** 61440 kHz (~25% of expected value)

The display was running at approximately one quarter of the required frequency.

#### 14:56:58.336 - DPLL State Verification Failure

**Expected DPLL State:**

multiplier: 16, tx_clk_div: 0
pll[0-19] = 0x0 (all registers zeroed/uninitialized)
```

**Analysis:** The Display PLL registers were either never initialized or were reset to zero. The fractional divider was disabled and the multiplier was set to a minimal value, resulting in 1/4 of the required clock frequency.

### Phase 3: Login Attempts and Resolution

#### ❌ Login Attempt #1 - 15:00:07 - FAILED
```
gdm-password][70848]: pam_sss(gdm-password:auth): authentication failure; logname=pstourac uid=0 euid=0 tty=/dev/tty1
gdm-password][70848]: pam_sss(gdm-password:auth): received for user pstourac: 7 (Selhání autentizace)
gdm-password][70848]: gkr-pam: the password for the login keyring was invalid.
audit[70848]: AUDIT1100 pid=70848 uid=0 auid=26519 ses=2 msg='op=PAM:authentication grantors=? acct="pstourac" exe="/usr/libexec/gdm-session-worker" res=failed'
```

**Note:** Authentication failed not due to incorrect password, but because the display was non-functional and user could not see/interact with login screen properly.

#### ❌ Login Attempt #2 - 15:00:13 - FAILED
```
gdm-password][71033]: pam_sss(gdm-password:auth): authentication failure; logname=pstourac uid=0 euid=0 tty=/dev/tty1
gdm-password][71033]: pam_sss(gdm-password:auth): received for user pstourac: 7 (Selhání autentizace)
audit[71033]: AUDIT1100 ... res=failed
```

Identical failure pattern. Display still non-functional.

#### ✅ Login Attempt #3 - 15:00:19 - SUCCESS
```
gdm-password][71049]: pam_sss(gdm-password:auth): authentication success; logname=pstourac uid=0 euid=0 tty=/dev/tty1
gdm-password][71049]: gkr-pam: unlocked login keyring

audit[71049]: AUDIT1101 ... msg='op=PAM:accounting ... res=success'
audit[71049]: AUDIT1110 ... msg='op=PAM:setcred ... res=success'
```

**What changed:** User triggered a display mode switch by locking/unlocking screen or switching virtual terminals, which forced i915 driver reinitialization. DPLL was properly configured on reinit, display became functional, and authentication succeeded.

#### 15:00:20 - Normal Session Started
```
gnome-shell[6042]: Enabling extension do-not-disturb-while-screen-sharing-or-recording
```

GNOME session loaded successfully with no further display errors.

|-----------|------------------------------|------------------------------|
| **Port Clock** | 61440 kHz (25% of normal) | 243000 kHz (correct) |
| **Pixel Rate** | 38971 Hz (unusable) | 154130 Hz (correct) |
| **PLL Clock** | 61440 kHz | 243000 kHz |
| **PLL Fractional** | Disabled (fracen: no) | Enabled (fracen: yes) |
| **PLL Multiplier** | 16 | 253 |
| **PLL TX Divider** | 0 | 2 |
| **PLL Registers** | All 0x0 (uninitialized) | Properly configured |
| **Display State** | Frozen/unreadable | Functional |
| **Page Flips** | Continuous timeouts | Normal operation |
| **Transcoder** | Timeout on disable | Normal operation |
| **Authentication** | Failed (UI non-functional) | Successful |

---

## Root Cause Analysis

### Primary Issue: DPLL Initialization Failure

The Display PLL (Phase-Locked Loop) clock generator failed to initialize properly, resulting in:

1. **PLL registers zeroed** - All 20 PLL configuration registers remained at 0x0
2. **Minimal multiplier** - Set to 16 instead of required 253
3. **Fractional divider disabled** - fracen=no instead of fracen=yes
4. **TX clock divider zero** - tx_clk_div=0 instead of 2
5. **1/4 frequency operation** - 61.44 MHz instead of 243 MHz

This resulted in the display running at approximately 25% of the required frequency, making the screen frozen or unreadable.

### Secondary Effects

- **Page flip timeouts** - GPU unable to synchronize frame updates with incorrect display frequency
- **PHY communication failures** - Physical layer unable to establish proper DP link
- **Transcoder errors** - Display pipeline unable to shut down properly
- **Desktop environment timeouts** - Mutter/GDM unable to configure display properties
- **Authentication failures** - User unable to interact with non-functional login screen

## Additional Context

**Total kernel graphics errors:** 94 log lines between 14:56:45 - 14:59:51  
**Post-recovery errors:** 0 (no i915 errors after display reinitialization)

**Other system notes:**
- Concurrent netbird service failures (unrelated, permission issue)
- System otherwise stable after successful login

---

## Expected vs Actual Behavior

**Expected:** Display PLL should initialize correctly on boot/resume with proper clock frequencies for the connected eDP panel.

**Actual:** DPLL initialization failed, resulting in:
- PLL registers remaining zeroed/uninitialized
- Clock running at 25% of required frequency
- Non-functional display preventing user login
- Recovery only possible through forced display reinitialization

I'm experiencing the same issue since I updated to kernel 7.0.x. I tried both `i915` and `xe` drivers, same issue on both. 

Here https://bbs.archlinux.org/viewtopic.php?pid=2297604#p2297604 is this commit mentioned that could be possibly fixing this issue: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=afe3f7471623.

Hi.

I have the same problem with wakeup from suspend. The same situation as mentioned by others - when suspended for shorter duration (~10-20 min.) it wakes up fine, but longer sleep (~1+ hrs) tends to lock and a forced reboot is the only way out.
Laptop is also a thinkpad, same class as previously mentioned, but a newer generation - T1g Gen 8, having Intel Core Ultra 9 285H vPro with Intel Arc 140T GPU and i915 driver in use.

Kernel: Linux fedora44host 7.0.8-200.fc44.x86_64 #1 SMP PREEMPT_DYNAMIC Fri May 15 14:03:46 UTC 2026 x86_64 GNU/Linux
journal snippet of the crash: https://pastebin.com/BR8HnU7R

A potential fix for this issue is in all 7.0.9 kernels if you want to give those a try.

I've tried -200 and -202 kernels, I assume you're referring to "drm/i915/dp_tunnel: Don't update tunnel state during system resume (Imre Deak)" and it didn't work for me and I've sent new logs to Intel upstream (https://gitlab.freedesktop.org/drm/i915/kernel/-/work_items/15992) but they didn't come back yet.

Yeah, I can confirm that with the 7.0.9-202.x kernel the issues seems to be fixed. Thank you!

I can confirm that suspend / resume works for me now on 7.0.9-202.fc44.x86_64.
I didn't try to see if it recovers from screen blanking when on screensaver.

I'm also affected by this issue with the company Lenovo P1 G7 laptop. Please address ASAP :pray:

Multiple people have confirmed the fix in 7.0.9 and one user has said this did not fix it for them. Clearly there are multiple issues here

Okay, it's probably my bad, I never experienced lockups, and I was referring to the black screen on wake as in https://bugzilla.redhat.com/show_bug.cgi?id=2464080, I lost track a little bit where we discuss what. Just to clear up things: I **do not** experience lockups on 7.0.9-20x kernels, but the black screen issue is still there.

I can confirm that I'm still seeing kernel panics and black screen when external monitor attempts to wake up after going into power-save mode and powering off when the screen locked, even with 7.0.9-202.fc44.x86_64.  I'm seeing the same RIP: 0010:verify_crtc_state+0x2b9/0x4e0 [i915].  This is in an Arrow Lake GPU:

These are the two stack traces that occur around 11 seconds after moving my mouse to unlock the screen:

How did you capture the traces? I can try to capture traces on my P1 G7 in case that helps.

*** Bug 2476974 has been marked as a duplicate of this bug. ***

I have spoken too soon. While my Thinkpad P1 Gen7 survived a short suspend it did not survive the overnight suspend with 7.0.9-202.fc44.x86_64.
Same symptoms and oops recorded in the journal.

The short suspend was: unplug monitor, close lid, wait for laptop to blink that it suspended, count to 3 and reopen the lid.


I got kernel 7.0.9-204.fc44.x86_64 this morning and I tried a few minutes suspend and it survived that:
May 21 09:08:49 sibiu.str.redhat.com kernel: PM: suspend entry (s2idle)
May 21 09:08:49 sibiu.str.redhat.com kernel: Filesystems sync: 0.030 seconds
May 21 09:21:07 sibiu.str.redhat.com kernel: Freezing user space processes
May 21 09:21:07 sibiu.str.redhat.com kernel: Freezing user space processes completed (elapsed 0.002 seconds)

So 7.0.9-204.fc44.x86_64 worked for a 12 minutes suspend on my Thinkpad P1 Gen7.
I do not see any i915 oopses nor errors nor warnings. i915s mentions after the resume are only:

@Pau: The journal is not getting corrupted with the oops so after the reboot you can look at the oops there with `journalctl -b -1`.

Definitely the issue is still persisting with 7.0.9-202.fc44.x86_64 on on a Lenovo P1 Gen7 (00:02.0 VGA compatible controller: Intel Corporation Meteor Lake-P [Intel Arc Graphics] (rev 08)) 
The only current workaround is to disable screen blanking

The issue with screen blanking is still there on my Thinkpad P1 Gen7 running 7.0.9-204.fc44.x86_64 even though the 12 minutes suspend/resume this morning was successful.

I have attached my "journalctl -b -1" output starting with the above lines.

I can confirm the same failure pattern on another Lenovo ThinkPad P1 Gen 7.

SYSTEM:
- Lenovo ThinkPad P1 Gen 7
- Product Name: 21KWS49V0G
- BIOS: N48ET33W (1.20), 2026-03-02
- Fedora 44 Workstation
- Kernel affected: 7.0.9-204.fc44.x86_64
- GNOME Shell 50.1 / Mutter 50.1
- Wayland session
- Intel Meteor Lake / i915 display path
- ThinkPad Thunderbolt 4 Dock connected
- External display setup through the dock

SYMPTOMS:
- After lock / idle / resume, the desktop becomes almost unusable.
- Switching screens can take several minutes.
- Mouse movement and GNOME UI become heavily delayed.
- Alt-Tab / GNOME Shell interactions freeze or respond extremely slowly.
- In my case the system is not always fully dead immediately, but the display/UI stack enters a broken state and usually requires reboot to recover properly.

TRIGGER / REPRODUCTION:
- The issue appears after lock/idle/resume with the dock connected + leaving it for longer period.
- I also observed that after leaving Slack fully closed during a longer idle period, the session resumed normally; then starting Slack desktop triggered the freeze within ~10 seconds.
- I do NOT think Slack is the root cause. It looks more like Slack/Electron can trigger display/GPU activity which exposes the underlying i915/DRM/KMS issue after resume.
- The kernel logs point clearly to the display pipeline, not to Slack itself.

Relevant journalctl errors from the affected boot:

Later, the system continued showing repeated i915/KMS timeouts:

kernel: i915 0000:00:02.0: [drm] ERROR flip_done timed out
kernel: i915 0000:00:02.0: [drm] ERROR [CRTC:149:pipe A] commit wait timed out

This strongly matches the existing bug description and previous logs attached here: i915 / DRM / KMS display pipeline regression around lock/resume/display reconfiguration on kernel 7.0.x.

My current boot entries are:

7.0.9-204.fc44.x86_64 - affected
7.0.6-200.fc44.x86_64 - affected
7.0.4-200.fc44.x86_64 - I don't remember, 80-90% affected
6.10.3-200.fc40.x86_64 - NOT affected


Since this bug is described as a regression from working 6.19.x kernels to broken 7.0.x kernels, I will try to test with an older kernel as a workaround/confirmation. If a known-good Fedora 44 6.19.x kernel is available, that would probably be the most useful comparison point. I would not treat Slack as the root cause - at most as a user-space trigger for the underlying i915/DRM/KMS regression.

RECOMMENDATION FOR AFFECTED USERS: 
If possible, boot a known-good pre-7.0 kernel, especially 6.19.x, until the i915 regression in the 7.0.x kernel series is fixed.

Kernel 7.0.9-300 (WORKING):
  Contains 3 specific Intel i915 graphics patches that are not present in kernel 7.0.10-200:

  1. drm/i915/dp_tunnel: Don't update tunnel state during system resume (Imre Deak)
    - Key patch for proper resume - doesn't update DisplayPort tunnel state during suspend wake-up
  2. drm/i915/cx0: Clear response ready & error bit (Suraj Kandpal)
    - Clears error bits in CX0 PHY (DisplayPort physical layer)
  3. drm/i915/pps: Enable panel power earlier (Mika Kahola)
    - Enables panel power earlier in the initialization process

  Kernel 7.0.10-200 (NOT WORKING):
  Is clean upstream 7.0.10 without these Fedora-specific patches. The log shows these errors:

  i915 0000:00:02.0: [drm] *ERROR* Failed to get ACT after 3000 ms, last status: 04
  gnome-shell: Page flip failed: drmModeAtomicCommit: Invalid argument
  gnome-shell: Failed to post KMS update: drmModeAtomicCommit: Invalid argument

I received a reply from an engineer at Lenovo, regarding this upstream issue: https://gitlab.freedesktop.org/drm/i915/kernel/-/work_items/14469
who said:

 Based on the latest investigation with Intel, the issue has been identified as related to the PCODE firmware (part of the BIOS package). A fix has already been included in the MR3 BKC release.
Key details:

    Root cause: PCODE firmware (BIOS component)
    Fix: Included in MR3 BKC (PCODE version v102.807f.0.5080)
    Availability: Integrated in BIOS release (e.g., P14s G5 (R2DET41W and later) P1 G7 (R2DET41W and later))
    Status: Intel backend has confirmed the fix; validation is ongoing due to low repro rate

> Kernel 7.0.9-300 (WORKING):

> kernel 7.0.10-200:

Yes, because 7.0.10 was built before anyone gave feedback on the test kernel I had built

kernel 7.0.10-201 includes the fixes and it seems to be available in updates! I'm installing it

For affected versions it helps a lot:

grubby --update-kernel=/boot/vmlinuz-7.0.9-204.fc44.x86_64 --args="i915.enable_psr=0"

Finally. Kernel 7.0.10-201 works prefectly.

I will also confirm kernel-core-7.0.10-201.fc44.x86_64 has completely resolved the blanking issue, with all i915.enable_* kernel parameter workarounds removed.

For the past 24  hours since the update, 7.0.10-201  has been working fine and has survived several blanking sessions

It seems this problem is fixed for all or most people. If you still encounter these issues with kernel 7.0.10-201 and latest firmware, please open a new bug, thanks.
