This occurs seemingly randomly, and causes dead lock where the graphics stack is unable to continue painting frames, generally lasting for several minutes.

Hm, looks similar to bug #64431

Comment 2 Jani Nikula 2015-01-28 15:36:57 UTC

Please attach dmesg with drm.debug=14 module parameter set, from boot to the problem.

Comment 3 Jani Nikula 2015-02-11 14:29:54 UTC

Might be a dupe of bug 88381. Long time no hear from the reporter, closing anyway. Please reopen if the problem persists with current kernels, and provide the info requested in comment #2. Thanks.
