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

This is true story.
Anyway, it blows up, see below.
Kernel is latest Linus tree, top commit is:

I can bisect if you don't see it immediately why it blows up.

well, that hardware is ancient ^^.
Interesting to see that even that old stuff is still used.

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://lore.kernel.org/all/CA+QYu4rt2VHWzbOt-SegA9yABqC-D36PoqTZmy6DscWvp+6ZMQ@mail.gmail.com/
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.

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.

Well, "used" is a stretch.
This is my way of testing on K8 as pretty much all the big K8 boxes to
which I had access to, got decommissioned so this baby is the only K8
real hw I have now. :-)
Lemme test your patch.
