Thanks for confirming this. The fix should make it to -rc5.

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.
