--- Comment #62 from Randune (randyk161 at gmail.com) ---
I've been getting "ring gfx timeouts" for some time (See comment 35), most of
the time it's when the computer has not had any input for a while (while I'm
away from it).  When it freezes I can SSH into it but when I try to do a:
"shutdown -h now" it boots me out of SSH as it should but the computer never
seems to actually shutdown.

I've tried many different kernel parameters but no luck so far.  I'm now trying
the amdgpu.runpm=0 as suggested here: https://wiki.archlinux.org/title/AMDGPU
(at the very bottom of the page: Issues with power management / dynamic
re-activation of a discrete amdgpu graphics card) I haven't seen any
performance repercussions yet. I'll just have to wait it out and see.

For my system specs see my previous comment 35.
