Hi folks,
so this is a *very* old K8 laptop - yap, you read it right, family 0xf.

This is true story.
well, that hardware is ancient ^^.
Interesting to see that even that old stuff is still used.
Anyway, it blows up, see below.
Kernel is latest Linus tree, top commit is:
a33f5c380c4b ("Merge tag 'xfs-5.17-merge-3' of
git://git.kernel.org/pub/scm/fs/xfs/xfs-linux")
I can bisect if you don't see it immediately why it blows up.
Immediately I see that code is called which isn't for this hardware
generation.
This is extremely odd because it means that we either have recently
added a logic bug or the detection of the hardware generation doesn't
work as expected any more.
Please bisect,
Christian.
I'm see panics like this one as well on multiple systems in lab (e.g.
ProLiant SL390s G7,
PowerEdge R805). Looks same to what Bruno reported here:
https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Flore.kernel.org%2Fall%2FCA%2BQYu4rt2VHWzbOt-SegA9yABqC-D36PoqTZmy6DscWvp%2B6ZMQ%40mail.gmail.com%2F&data=04%7C01%7Cchristian.koenig%40amd.com%7C42f29e6eb93243584c2108d9d9953e25%7C3dd8961fe4884e608e11a82d994e183d%7C0%7C0%7C637780057291895847%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000&sdata=HO5dYKo7kQHtneS%2F5ftl9KobWa%2BIjgXKjf7SXe0aRcw%3D&reserved=0
It started around 8d0749b4f83b - Merge tag 'drm-next-2022-01-07',
running a bisect atm.
Not necessary any more. That is probably caused by commit
drm/radeon/radeon_kms: Fix a NULL pointer dereference in
radeon_driver_open_kms() ab50cb9df8896b39aae65c537a30de2c79c19735.
I'm getting other bug reports for that one as well. Going to take a look.
Regards,
Christian.
