I experience this at least once per day on a Ubuntu 14.04-installation with LTS hardware enablement upgrade to kernel 3.16 (and newer Xorg components). Typically, full screen video playback will suddenly freeze (audio continues to play). At that point I must switch to VT 1, which takes about a minute to happen, and then back to VT 7, to unfreeze the desktop. The error in the kernel log does not appear immediately, but rather after having switched to VT 1 (intel_crtc_wait_for_pending_flips+0x171/0x180). Typically, the app that was playing video will crash.
