error dump

Hello,

When I leave the modesetting driver parameter AccelMethod to default, I am very
easily getting a GPU hang, I just need to run:

startx fvwm

I get an X session with eDP-1 on the left and DP-2 on the right, which I change
with

xrandr --output eDP-1 --auto --output DP-2 --auto --above eDP-1

and then I get a GPU hang. I am now attaching the /sys/class/drm/card0/error
output, will also attach other logs.
