Hi Robin, The easiest way for you to collect more information is to wait until it freezes again, ssh into the sick box, and run the command /usr/share/apport/apport-gpu-error-intel.py. This will cause a new bug to get filed (after you reboot), with the gpu dump and logs, so I'll close this bug report out so we can focus on the new one.
