I am experiencing intermittent screen, mouse, and keyboard freezes when using xorg and the integrated i915 Intel video. Here is the relevant snippet from journalctl.

I followed some advice from ArchWiki’s Intel graphics article. I uninstalled xf86-video-intel because of its apparent instability, and I am presumably using KMS. I am unclear why or how early KMS would matter. I tried the kernel parameters i915.enable_guc=2 and i915.enable_psr=0 to no avail. The former gave me the dmesg error “GuC is not supported!”
I also tried [this advice on reddit] when searching for my error message. Running sensors-detect didn’t change anything.
What else should I try?
