Periodically when firefox is running my laptop freezes for a few seconds. I decided to try running firefox from terminal to see what shows up when that happens, and I always get:
[GFX1-]: GFX: RenderThread detected a device reset in PostUpdate
Google search shows no useful results, either.
Does anyone know what might be causing this?
I’m not sure but a lot of us are running with
options i915 enable_psr=0 set in
/etc/modprobe.d/i915.conf. I think that you will need to regenerate your initrd after adding that, I think with
sudo update-initramfs -u. You can
sudo cat /sys/module/i915/parameters/enable_psr to check to make sure that it is set correctly.
There is a whole thread about graphics hangs here: Hard freezing on Fedora 36 with the new 12th gen system - #175 by Elmo

EDIT: I don’t know what kernel you are running but 5.18 is the first one that knows how to properly schedule the 12th gen cores: Intel's Thread Director Coming to Linux 5.18 to Fix Alder Lake Performance Issues | Tom's Hardware
I have it once in a week too, I am on chrome ubuntu 22.04
Deactivating ecores from bios helped.
The first thing to try is what PDXTabs suggested. And per their suggestion, make sure you’re on a compatible kernel:
Check your kernel version with:
Share output here.
sudo gedit /etc/modprobe.d/i915.conf
options i915 enable_psr=0
Click Save. Then still in the termimal:
sudo update-initramfs -u
Now restart your computer.
Sorry for the late update, but I actually seem to have resolved my issue by turning off hardware acceleration in firefox. Since I made this update a few weeks ago, I haven’t had any weird freezing events.
Fantastic, I appreciate the update.
