Description Gurenko Alex 2025-09-26 13:39:49 UTC

1. Please describe the problem: Lenovo P1 Gen7 laptop does not boot with kernel 6.16.9. This is a Fedora 42 KDE installation with LUKS FDE.


2. What is the Version-Release number of the kernel: kernel-6.16.9-200.fc42


3. Did it work previously in Fedora? If so, what kernel version did the issue
   *first* appear?  Old kernel kernel-6.16.8-200.fc42 works fine


4. Can you reproduce this issue? If so, please provide the steps to reproduce
   the issue below:

   - Install 6.16.9 kernel
   - Rebooot
   - Select new kernel in grub

5. Does this problem occur with the latest Rawhide kernel? To install the
   Rawhide kernel, run ``sudo dnf install fedora-repos-rawhide`` followed by
   ``sudo dnf update --enablerepo=rawhide kernel``: Have not tried it yet


6. Are you running any modules that not shipped with directly Fedora's kernel?: no


7. Please attach the kernel logs. You can get the complete kernel log
   for a boot with ``journalctl --no-hostname -k > dmesg.txt``. If the
   issue occurred on a previous boot, use the journalctl ``-b`` flag.

There is no boot attempt in logs with 6.16.9 kernel and the screen is black, so hard to tell what is happening.

Reproducible: Always

Comment 1 Gurenko Alex 2025-09-26 13:54:58 UTC

kernel-6.17.0-0.rc7.56.fc43 boots fine

Comment 2 Justin M. Forbes 2025-09-26 14:12:15 UTC

What happens if you edit the kernel command line and remove rhgb and quiet?

Comment 3 Gurenko Alex 2025-09-26 15:04:06 UTC

@jforbes there was nothing obvious after removing rhgb and quiet, at least no errors that I can see (I can send a link to a video), but one line about blacklisting i915 reminded me that I have xe driver enabled instead of i915 with `i915.force_probe=!7d55` and `xe.force_probe=7d55`. After removing it it booted fine. There are few commits in 6.16.9 what touches drm/xe.

Comment 4 Gurenko Alex 2025-09-26 15:26:11 UTC

Ah, found a relevant issue upstream: https://gitlab.freedesktop.org/drm/xe/kernel/-/issues/6239

Comment 6 Gurenko Alex 2025-09-29 17:35:17 UTC

I would raise the priority then, since Lunar Lake (at least) relies on Xe driver solely.

@jforbes is it possible to try to revert mentioned specific commit 97207a4fed5348ff5c5e71a7300db9b638640879 (drm/xe/guc: Enable extended CAT error reporting) ?

Comment 7 Justin M. Forbes 2025-09-29 17:43:31 UTC

It is staged to be reverted with the 6.16.10 kernel this week.

Comment 8 Mihai Harpau 2025-09-29 17:44:53 UTC

It seems there are two commits which must be reverted:

"Yes, reverting both dd1a415dcfd5 "drm/xe/guc: Set RCS/CCS yield policy" 
and 97207a4fed53 "drm/xe/guc: Enable extended CAT error reporting" from 
6.16.y fixes the issue for me."

I suppose those reverts will be in next stable kernel release.

Comment 9 Justin M. Forbes 2025-10-06 17:55:35 UTC

6.16.10 has been in updates testing for a while and should get to stable today. It has the reverts.

Comment 14 Mihai Harpau 2025-10-06 19:14:14 UTC

I confirm that T14 Gen6 Lunar Lake works fine on kernel 6.16.10.

Comment 15 Gurenko Alex 2025-11-06 14:05:01 UTC

Issue was resolved as of 6.16.10 and xe driver is currently functional.
