Bug Description
Very strange symptom: most of time, system boots up normally, X starts and everything works as good as expected. But after 5 minutes or more maybe 1 hour, attached screens blinks for a moment, and warning shows up in dmesg:

At this time, nothing particularly worrisome happen.
More than one hour later, X crashes and restarts. This is worrisome, because it can cause unsaved data loss.
This bug introduced in 15.10 (linux 4.2). Everything was fine in 15.04 (linux 3.19).
Its more likely a kernel -> intel-drm bug than X. Kernel warning & error message occur in Gentoo too (linux 4.2 and 4.3). Everything fine in 4.0.
