Sound like my problem: kernels above 5.4.88 freeze/crash. Would be great if 
we could isolate the troublemaker and fix the problem.

You can check driver and firmware version with:
[root@dom0]# modinfo i915  

Do you simply use working (i.e. old) driver/fw binaries with a recent 
kernel, or did you patch/install from source?
