Hello! ThinkPad T14S and CachyOS is randomly hard locking. I get a black display with frozen cursor most recently Log file displays: Pageflip timed out! This is a bug in the amdgpu kernel driver Thank you

See over here; [image] [Tutorial] Mitigate GFX Crash/Lockup (apparent freeze) with amdgpu FAQ and Tutorials There are numerous bug reports and even more possibly-related forum posts and anecdotes floating around about a surprisingly common problem with amdgpu …

Thanks, I responded there with more detail although my symptoms do not quite match what you’ve quoted. My tty do not seem accessible once the freeze takes hold, nothing short of a long-press powerdown will work (so far that i’ve found)
