I fear I may have contributed to this confusion by filing the original
report by way of apport-gpu-error-intel.py rather than ubuntu-bug. I
(perhaps wrongly) inferred from the symptoms that there was a GPU lockup,
even though the error handler hadn't triggered, or else that the GPU dump
would be useful in diagnosing the problem regardless.
