I probably made a mistake while backporting some non-trivial changes for

Hi Andreas!
I will verify if this fixes this issue, though I will still bet that the
ibt=on in the new kernels is the cause. Apparently in newer kernels,
Indirect Branch Tracking [1] support was enabled by default [2] in the
kernel, but older nvidia drivers do not have this support and end up
with undefined behaviour instead. [3] On newer drivers they added
support [4]
This breaks 11th generation and newer intel CPUs with older nvidia
cards. Maybe not so common :-)
Please test the new driver version on a recent kernel once it gets
available on your mirror in a few hours.
Will test in few hours.
