Current drm-intel-fixes is just six commits on top of -rc4, and it's very hard for me to believe any of those would cause the symptoms you see. I presume the problem, whatever it is, is already in -rc4. That, of course, is not a happy thing per se, but please don't block the current batch of fixes by making unsubstantiated claims. Please do file a bug about that issue over at [1] so we don't hijack this thread. Thanks, Jani.
