First step is to try 2.21.10 as that most likely has the bug fix:

    sna/dri: Handle fast double flips across mode changes

But Zaphod raises a few other concerns.
Comment 7 Chris Wilson 2013-06-23 06:37:54 UTC
Fixed up the warnings from Zaphod trying to drop drmMaster too often, can you please check with xf86-video-intel.git?
Comment 8 Chris Wilson 2013-07-17 11:50:29 UTC
Timeout; presuming to be the known and fixed bug with chaining fast flips.
