When I using Arch Linux, sometimes the gnome-shell hangs and recover after a few seconds, I notice there are something in the output of dmesg
> [19302.586519] i915 0000:00:02.0: GPU HANG: ecode 9:0:0x00000000, hang on rcs0

So I paste the content in /sys/class/drm/card0/error to https://fars.ee/T7Z5/
I hope it can help developers to find what's wrong for my GPU.
If need more info, I will try to provide it.
I notice something new in dmesg:
After recover, I found there is a message:
> [24636.509281] i915 0000:00:02.0: Resetting rcs0 for hang on rcs0
