This is /sys/class/drm/card0/error
I was using Xilinx ISE 10.1 SP3 (x86_64) on my Arch Linux machine. I was drawing a wire while the user interface suddenly froze. I tried switching tabs (I'm using i3 as windows manager) but nothing happened. Then after a few seconds everything is back to normal. I checked the kernel log by typing dmesg, and discovered the following message. I thought it might be good to file a bug report.
[24917.579505] [drm] GPU HANG: ecode 9:0:0x86dffffd, in Xorg , reason: hang on rcs0, action: reset
[24917.579506] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[24917.579507] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[24917.579507] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[24917.579508] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
