GPU Hang (ecode 8:1:0x85dffff9)
GPU Hang bug, I think introduced in the 5.5 kernel. (It was there in 5.5.4, and absent in 5.4.8 -- I haven't done a careful bisection yet, sorry.)
The hang happens when I boot up and first run startx
. It finishes after about a minute. Sometimes I open terminal and then it hangs again. Once the first minute or so is done, though, the computer acts normally (almost -- see below).
Attached are the outputs of:
dmidecode
journalctl | tail -nsomething
uname -a
cat /sys/class/drm/card0/error
There's one other phenomenon that appeared at exactly the same time: the game warzone2100
no longer works. Intro screen is a black screen, instead of any graphics showing up. No errors show up anywhere.
