I have this:

https://community.frame.work/t/tracking-hard-freezing-on-fedora-36-with-the-new-12th-gen-system/20675?page=18


6.1.7-200.fc37.x86_64 / 12th Gen Intel(R) Core™ i7-1260P

No i915 tunnings! But with intel_idle.max_cstate=2 while booting

With this Since 6.1.17 – I have started getting hangs – but w/o the garbled
screens and trash and garbage on my screens. Garble screen hangs will,
seemingly, eliminated with intel_idle.max_cstate=2.

With 6.1.17, I started to just getting freezes/hangs; no garbled screens.

So maybe in my situation I did have some problems related the sleep states; but
now perhaps I am now also bumping into the intel GPU issues many have noted
here:

booting now with: intel_idle.max_cstate=2 i915.enable_psr=0

I seem to have some stability back.

NOTE: There is maybe some correlation between this (new to me) hang and Zoom
with web cam active. Too early to tell at this point.
