I have this exact same problem. My computer logs :

 WARNING: CPU: 3 PID: 659 at /build/buildd/linux-3.19.0/drivers/gpu/drm/i915/intel_display.c:9705 intel_check_page_flip+0xa2/0xf0 [i915]()

continually with the 3.19.0-7 and 3.19.0-8 kernels in the -lowlatency kind.

It occurs sometime while resuming from pause in the -generic kind of kernel.

I concur : https://bugs.freedesktop.org/show_bug.cgi?id=89321 seems to have the answer. Even a patch there.
