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 :-)

Will test in few hours.
