Comment # 4 on bug 1205698 from Thomas Renninger

> Also, curious about which CPU model you had that issue with.
Yep, please attach /proc/cpuinfo output.

> Full disclosure: I'm running self-built kernels, currently 5.15.78
Hmm, this is somewhat problematic... If the problem is related to an old or
specific kernel version/option, we spend time for nothing.
You should really install the tested kernel fitting/provided by the
distribution you are running on. At least reproduce the issue there once.
