As a non-expert, non-canonical answer (in the non-commercial sense of the word canonical), I would primarily be interested in saving the contents of /sys/kernel/debug/dri/0/i915_error_state You can decompile that with "intel_error_decode $file" Also, note if there are any interesting messages in dmesg pertaining to drm / gem / i915 (caps or non-caps for all), and anything unusual in the end of /var/log/Xorg.0.log or /var/log/Xorg.0.log.old if your X server has restarted. The error state ought to be relevant to the hang assuming you've not rebooted or had any subsequent hangs.
