<pre>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</pre>
