Description Freddy Willemsen 2021-03-07 10:26:08 UTC

requested journalctl.

1. Please describe the problem:
On my main laptop (Dell Latitude E5570, BIOS 1.23.3 since april 2020) kernel-5.11 panics during boot. A Latitude 5480, Latitude E5510 and some old Asus laptop boot just fine. I am using a cleanly installed Fedora 33 on XFS.
After a day of debugging (disabling SMT, disabling Wifi, disabling ethernet, disabling audio, etc) I managed to boot using acpi=off. Tried acpi_osi=Windows, acpi=ht, pci=noacpi, acpi=noirq, pnpacpi=off, noapci, nolapic , acpi=strict as well, none of them work, only acpi=off boots (though giving me a single core computer without SMT).

2. What is the Version-Release number of the kernel:
Currently 5.11.3-50.fc33.x86_64. I recompiled all fc34 5.11 kernels as well, same issue.

3. Did it work previously in Fedora? If so, what kernel version did the issue
   *first* appear?  Old kernels are available for download at
   https://koji.fedoraproject.org/koji/packageinfo?packageID=8 :
All 5.11 kernels exhibit this behaviour. All 5.10 kernels work fine. I even tried 5.12 (kernel-rawhide-nodebug) and that one works as well.

4. Can you reproduce this issue? If so, please provide the steps to reproduce
   the issue below:
Boot with any 5.11 kernel.

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``:
No, kernel-5.12.0-0.rc1.162.fc35.x86_64 boots fine.

6. Are you running any modules that not shipped with directly Fedora's kernel?:
Tried with and without, no change.

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.

Comment 4 Freddy Willemsen 2021-03-07 10:36:14 UTC
Used rd.break up to cleanup to figure out where the panic occurs. It seems to appear right after the the rd phase, during the sysinit.target.

Tried using 'acpi.debug_layer=0x2 acpi.debug_level=0xffffffff' as well but CONFIG_ACPI_DEBUG is not set.

I can not really figure out why every bit of hardware works just fine, except for my main laptop, which serves me well for over 4 years now.

Comment 5 Freddy Willemsen 2021-03-07 10:43:50 UTC
Not sure if it is relevant, but I copied the root disk to an external USB drive. Then booting 5.11 on my Dell E5570 it panics, using the same disk on a Dell 5480 it works just fine.

Comment 6 Freddy Willemsen 2021-03-10 10:56:49 UTC
Both kernel-5.11.4-50.fc33 and kernel-5.11.5-50.fc33 exhibit the exact same behavior, no change there.

Comment 7 Freddy Willemsen 2021-03-17 22:51:38 UTC
no changes for kernel-5.11.7-200.fc33, still panics on boot. 
kernel-5.12.0-0.rc3.170.fc35.x86_64 from kernel-rawhide-nodebug does work in general (not thoroughly tested).

Comment 8 ryanpg 2021-03-18 20:16:06 UTC
I had the same issue on a Dell Inc. Precision 7710 and kernel 5.11.3-300.fc34.x86_64. It was resolved with 5.12.0-0.rc3.20210318git6417f03132a6.171.fc35.x86_64 which boots fine

Offhand I'm not seeing what might be fixing it in 5.12...

Looks related to this:
https://bugzilla.kernel.org/show_bug.cgi?id=211895

Comment 10 Freddy Willemsen 2021-03-19 14:05:59 UTC
I tried the proposed patch from the bug report at kernel.org to no avail. As suggested there, adding 'modprobe.blacklist=dell_wmi_sysman' to the boot options makes kernel-5.11.7-200.fc33 bootable.

Comment 11 Jared Dominguez 2021-03-19 21:30:21 UTC
Perry, can you take a look at this?

Comment 12 Hans de Goede 2021-03-19 22:04:36 UTC
> Perry, can you take a look at this?

Note a fix for this has been posted upstream, but as I mentioned during the review, the fix contains a bug and a new fixed version of the fix is necessary:

https://patchwork.kernel.org/project/platform-driver-x86/patch/20210218191723.20030-1-mario.limonciello@dell.com/#23988825

Comment 13 Perry Yuan (Dell) 2021-03-20 14:42:10 UTC
(In reply to Jared Dominguez from comment #11)
> Perry, can you take a look at this?

This was one sysman driver crash issue that has been fixed by the patch Hans mentioned.
Seeing from Comment 9 , this seems like is a new issue of sysman driver

Comment 14 Hans de Goede 2021-03-20 18:57:32 UTC
I've prepared and posted a set of patches which deal with various problems with error-exit path cleanups and general robustness of the dell-wmi-sysman driver:

https://lore.kernel.org/platform-driver-x86/20210320143429.76047-1-hdegoede@redhat.com/T/#t

Note it is not entirely clear to me what is going on here, so I'm not sure if these patches fix things but hopefully they will help.

I've started a Fedora kernel test-build with these patches added here:
https://koji.fedoraproject.org/koji/taskinfo?taskID=64195453

Note this is still building ATM it should be done in about 2 hours.

See here for generic instructions for installing a kernel directly from koji (the Fedora build-system):
https://fedorapeople.org/~jwrdegoede/kernel-test-instructions.txt

Please give this kernel a test and let me know if it fixes things.

Perry, can you please test this test-build on hardware which actually supports the new WMI interfaces used by dell-wmi-sysman and checks that the dell-wmi-sysman still works correctly on that hardware?

###

What would also be helpful, independent of testing the patches, is if someone could boot a 5.11 kernel with dell-wmi-sysman blacklisted to avoid the problem.

And then:

1. Switch to a text-console
2. ssh into the machine and run dmesg -w
3. ssh into the machine a second time and run: "sudo modprobe dell_wmi_sysman dyndbg"

And then collect log info from the "dmesg -w" and in case there are log messages on the text-console which did not make it into the ssh dmesg -w output, make a picture of those.

Comment 15 Hans de Goede 2021-03-20 19:50:28 UTC
Note the scratch/test kernel-build has completed building now, if someone can give this a test on one of the machines where 5.11 does not work that would be great.

Perry, can you please test this test-build on hardware which actually supports the new WMI interfaces used by dell-wmi-sysman and checks that the dell-wmi-sysman still works correctly on that hardware?

Comment 18 Hans de Goede 2021-03-21 11:08:49 UTC
Freddy, thank you for the tests and for the dmesg which you've attached on the kernel bugzilla.

I think I have a good idea now of why the crash is happening,
but I do still have a few more questions:

1. Can you do (while running the patched kernel):

ls -lR /sys/class/firmware-attributes/dell-wmi-sysman/

On the system where the driver actually loads (E5570) and copy and paste the output here ?

I wonder if the driver actually does anything there, or if one of my patches is wrong causing an empty "firmware-attributes" device to show up there.

2. Can you, with the patched-kernel do a "sudo modprobe dell_wmi_sysman dyndbg" on the system where the driver does not load (5480) and then collect dmesg output after that ?

3. When you boot an unpatched kernel on the 5480, does lsmod show dell_wmi_sysman being loaded? I think it may simply never load on that devices because it does not have the WMI GUIDs which the driver binds to.

4. Can you do: "ls /sys/bus/wmi/devices/" on the 5480 and copy and paste the output here?

Ok, so this is as I expected, your BIOS seems to advertise the functionality to set BIOS settings from within the OS, but it does not list any actual settings to change (which is what triggered the crash before). Interestingly enough it does seem to allow changing the BIOS-passwords from within the OS.

I'm not sure if that is intentional on Dell's side or not. I'll discuss with Dell how to proceed with this bit of the issue.

I've dropped the patch which allows the driver to still load even though there are no "attributes" to set for now; and I'll submit a merge-req to get the other patches (which will still fix the crash) added to the Fedora 5.11 kernels, so that affected machines will boot again.

Comment 21 Freddy Willemsen 2021-03-21 12:30:37 UTC
No problem, glad to be of service. Thanks for all the efforts in squashing this bug.
Look forward to the patched 5.11 fedora kernels.

Here is the merge-req for getting the fixes for this added to the Fedora 5.11 kernels:

Hi Hans
I got one sample which support sysman feature and will do the testing On Monday today. 
Dell have a new BIOS fixing previous driver issue and I need to flash the BIOS then i can test your kernel.

Hans.
I saw you update your patch to V2.
Could you share the V2 test kernel koji link ?
I can help to test that version as well.

The biggest difference in v2 is that I dropped this patch:
https://patchwork.kernel.org/project/platform-driver-x86/patch/20210321121607.35717-1-hdegoede@redhat.com/

Because that patch needs more testing, the rest is the same as v1, so please test the v1 kernel which actually has that patch:
https://koji.fedoraproject.org/koji/taskinfo?taskID=64195453

Comment 26 Perry Yuan (Dell) 2021-03-22 11:08:20 UTC
Tested Hans V1 test kernel on Dell new Mobile platform which flashed with new BIOS
The sysman driver works well and no issue found on that kernel.

Perry, thank you for testing this. I'll send a pull-req to Linus with the fixes soon. Once those have landed I'll add a comment that the fixes are now upstream to bug 1941416.

kernel-5.11.9-200.fc33 contains the patches from Hans and solves the issue without the blacklist workaround, tested on a Dell Latitude E5570 and a Latitude 5480. A big thanks to everybody involved!
As far as I am concerned this one can be closed.
