[Bug 1510723] [NEW] intel i915 driver segfaults: WARNING: ...drivers/gpu/drm/i915/intel_display.c:11100 intel_check_page_flip+0xfc/0x110 [i915]()

 

Public bug reported:

Continuing from https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1505242
100% reproducible.
Adding tags for upstream because I've already tested it and it's still the case for 4.3-rc7, just with a different line number, hope it'll not cause confusion.
