[Intel-gfx] eDP is black after screen rotate in kernel 3.19

Tue Apr 14 00:39:31 PDT 2015

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 ?

thanks
