I only use the integrated Intel graphics, the Nvidia card is unused.
There was no null pointer dereference with the previous kernel
(5.19.11-1 (2022-09-24)).
Besides the null pointer dereference above, suspend to RAM also no
longer works properly after the upgrade. I have not investigated that
further so far.

I only use the integrated Intel graphics, the Nvidia card is unused.
There was no null pointer dereference with the previous kernel
(5.19.11-1 (2022-09-24)).
Besides the null pointer dereference above, suspend to RAM also no
longer works properly after the upgrade. I have not investigated that
further so far.

At least this part is easy: after blacklisting the nouveau driver to

avoid the warning about the NULL pointer dereference, suspend works
again.

Can you verify if the issue is also present on 6.0~rc7-1~exp1?

I expect it does, but it's better to know then to assume.
There have been quite some commit under 'drivers/gpu/drm/nouveau' in kernel
6.0 and in 6.0.3 there have been several NPE fixes, although they didn't appear
directly related to your issue.
It could be, but it could also be that there are more.

I think I have the same problem than Angsar. And still reprocude it

Hello,
Reproduced (without much surprise) with 6.1.1-1~exp2.

see if I can reproduce the bug. Unfortunately, this kernel doesn't
boot (and I don't have much time to investigate).
