Hi Andrea,
Many thanks for the fixed kernel. I tried installing it with "sudo dpkg
-i --force-overwrite *" but it would not boot. I see multiple error
messages like "failed to validate module

I tried the suggested workaround of purging nvidia packages and running
ubuntu-drivers install. What I observed is that the nvidia-driver-510
packages were removed, and ubuntu-drivers subsequently installed

sudo apt-get --purge remove '*nvidia*'
sudo ubuntu-drivers install
solved the problem for me. I am in KDE running in 5.19.0-19-generic with
Nvidia 515 drivers.
Thanks a lot.

Hi Heinrich, I can see the following in your dmesg log:
NVRM: API mismatch: the client has the version 515.65.01, but
NVRM: this kernel module has the version 510.85.02
Can you follow these steps, please, so that we can rule out this being the main
problem?
Remove any nvidia package left on
So, it looks like there are multiple issues here. The NULL pointer
dereference bug that I see in comment #25 seems to be fixed by
458ec0c8f359 ("drm/i915: fix null pointer dereference"), but this can
happen only when i915 is used.
For the other problem(s) do you happen to have a kernel oops /
Hello Andrea,
As expected an i915 fix is irrelevant for a system without an i915 GPU.

Test kernel (5.19.0-19.19+i915fix) available here:
https://kernel.ubuntu.com/~arighi/lp-1991703/
It would be great if someone affected by this problem could test this
out. Thanks in advance!

Thanks Andrea for looking into the issue.
Would the code changed in 458ec0c8f359 ("drm/i915: fix null pointer
dereference") ever be executed on an AMD Ryzen processor with an Nvidia
card? Doesn't the driver framework detect that there is no i915 GPU?

This bug should be fixed by 458ec0c8f359 ("drm/i915: fix null pointer
dereference"), I'll prepare a test kernel with this fix applied on top
of 5.19.0-19.19.
