dmesg output please ? (you can attach long text outputs instead of pasting them, makes it easier to read).

hmm, need to see the message from the 'drivers/gpu/drm/i915/i915_irq.c:' report. Hunt for it in /var/log/messages, and attach that please. The actual bug is already reported (many times), so I'm just curious here to find out what is caused the tainted kernel.
(to clarify, that warning should be accompanied by a list of modules in the log)
