Description Ian Harding 2015-10-06 18:26:53 UTC 
We have many Dell Optiplex 380/390 which have run CentOS 6.5 happily for years.  We upgraded some to CentOS 7 and have intermittent screen flashing and occasional blue screen (not like Windows, the screen just goes shades of blue and locks up)

Saw this in the log and did it:

Oct  6 11:06:47 seattle154 kernel: [drm] GPU HANG: ecode -1:0x00000000, reason: Kicking stuck semaphore on render ring, action: continue
Oct  6 11:06:47 seattle154 kernel: [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
Oct  6 11:06:47 seattle154 kernel: [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
Oct  6 11:06:47 seattle154 kernel: [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
Oct  6 11:06:47 seattle154 kernel: [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
Oct  6 11:06:47 seattle154 kernel: [drm] GPU crash dump saved to /sys/class/drm/card0/error
Comment 1 Ian Harding 2015-10-06 18:31:18 UTC 
OK, so apparently you can't copy that "file" so I lost the contents of the crash dump.  I'll try again next time.
Comment 2 Chris Wilson 2015-10-06 19:45:56 UTC 
That dmesg GPU hang report is unrelated to the screen flashes and eventual freeze.

Timeout, closing. Please reopen if there is a next time.
