data from /sys/class/drm/card0/error
I was testing a qt-based app. The UI froze for several seconds, then resumed
without an issue. In dmesg, I've found the following:
[958940.926878] [drm] stuck on render ring
[958940.927417] [drm] GPU HANG: ecode 7:0:0x87dd7d10, in app [17354], reason:
Ring hung, action: reset
[958940.927418] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[958940.927419] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[958940.927419] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[958940.927420] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
[958940.927420] [drm] GPU crash dump saved to /sys/class/drm/card0/error
