Hi Merelin, unfortunately there are a variety of ways a system can lock up with this error message, but we need to get the dmesg and /sys/kernel/ debug/dri/ 0/i915_ error_state from point of failure (while system is locked up).
Easiest way is to let apport capture it directly, which it does automatically much of the time. I'll close this bug in hopes that next time it happens apport will catch it and you can file a new bug that way. If not, please manually collect the info and reopen this bug report.
