On one Broadwell machine with Ubuntu 15.04, eDP is black after running “xrandr –output eDP1 –rotate inverted”.
Only 3.19 kernel has such issue, 4.0 kernel doesn’t have such issue.
When this issue happens, I see the following call trace in dmesg:

Does anybody remember which commit in kernel 4.0 fixes this issue ?
