I tried kernel-3.14.20-100.fc19.i686 from Fedora's updates-testing and after
about an hour of crash-free YouTube I was about to state my cautious optimism
here, when the error occured again.  Unfortunately, I hadn't set up the
catch-the-files script then, so I have no data apart from /var/log/messages
that starts again with:

| Oct 10 01:59:23 passepartout kernel: [ 5488.004035] [drm] stuck on render
ring
| Oct 10 01:59:23 passepartout kernel: [ 5488.004043] [drm] GPU crash dump
saved to /sys/class/drm/card0/error
| Oct 10 01:59:23 passepartout kernel: [ 5488.004045] [drm] GPU hangs can
indicate a bug anywhere in the entire gfx stack, including userspace.
| Oct 10 01:59:23 passepartout kernel: [ 5488.004047] [drm] Please file a _new_
bug report on bugs.freedesktop.org against DRI -> DRM/Intel
| Oct 10 01:59:23 passepartout kernel: [ 5488.004049] [drm] drm/i915 developers
can then reassign to the right component if it's not a kernel issue.
| Oct 10 01:59:23 passepartout kernel: [ 5488.004050] [drm] The gpu crash dump
is required to analyze gpu hangs, so please always attach it.
| Oct 10 01:59:24 passepartout kernel: [ 5488.508033] [drm:i915_reset] *ERROR*
Failed to reset chip: -110
| [...]

Testing non-packaged kernels will take me a few days because I won't do that on
my (somewhat :-)) working system.

(If there is a stress test for the graphics system that is more reproducable
than watching YouTube, pointers are appreciated.  Spending literally an hour
without knowing if the different kernel has fixed the issue is very
unproductive as the looming blank screen prevents doing anything non-trivial
:-(.)
