When that happens, mount debugfs with 'mount -t debugfs none
/sys/kernel/debug', and grab the i915_error_state file from
/sys/kernel/debug/dri/0/.  There's a good chance a newer
xserver-xorg-video-intel or libgl1-mesa-dri has a fix for this though,
so that would be one thing to try.  Easier if you can find a reliable
reproducer though.
