Because everytime my system hangs / freezes I found something like
this in syslog:
[ 135.116721] i915 0000:00:02.0: GPU HANG: ecode 9:1:0x00000000, hang on rcs0
[ 135.116724] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 135.116725] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 135.116726] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 135.116727] The GPU crash dump is required to analyze GPU hangs, so
please always attach it.

etc, etc, etc, until I got tired and shutdown the computer using the
power button.
More people with my very same experience here:
https://gitlab.freedesktop.org/drm/intel/issues/673
> Other things to try:
> - update the microcode (package intel-microcode in non-free)
> - try with different, known good RAM
> - try with a different, known good and generously sized power source
> - update the motherboard BIOS
I always ran the intel microcode package, tried every bios update, and
I even changed the whole computer, so this is not the solution.
Thank you
