Too bad I turned off my machine later after I've caught that stack trace, so I can't give you the dump of i915_error_state, but I was checking both dmesg and xsession-errors and there was nothing unusual and no signs of error output from i915.

I'll try to catch it again and if I do I'll attach dmesg and dump of i915_error_state here.
