Hi, Sitsofe, you wrote in your bug report (#89108), that you've got a black screen, when you tried drm-intel-nightly branch. Do you have black screen with v4.0-rc1 on your eeepc? If so, is it similar to that I described here https://lkml.org/lkml/2015/2/3/594 ? As we both had drm_wait_one_vblank warnings, I assume that we have the same or similar chipsets. And your black screen could be potentially the same as mine. -- Best regards, Andrey Skvortsov PGP Key ID: 0x57A3AEAD
