I'm sorry I cannot get that file. First reason I have nothig in /sys/kernel/debug/ and second I cannot ssh to the computer because network is down(I use wicd and wifi connection, I guess it doesn't go on after resume).
See http://intellinuxgraphics.org/how_to_report_bug.html and in particular http://intellinuxgraphics.org/i915_error_state.html
I haven't been able to reproduce this. I've had some Intel drivers and Mesa updates since. I think you can close it for now, maybe I will reopen it if it happens again.
Ok, thanks for the update.
