If DUT connects both HDMI and DP displays, eDP/DP/HDMI screens are all blank. Official kernel 3.18.0 (commit b2776bf7149bddd1f4161f14f79520f17fc1d71d) has the same issue. Please retest with current drm-intel-nightly, and http://patchwork.freedesktop.org/patch/41360 Hi Jani, This issue happens only on 3.18 official kernel and drm-intel-fixes. drm-intel-nightly works. Do you suggest to test with latest drm-intel-fixes? Ville, do we need to find the commit to backport? This would require a reverse bisect.

But if the problem still happens with latest -fixes then a reverse bisect would be a good idea. I just stared at the fixes vs. nightly diff for a while and didn't see anything that would explain it. Tried on drm-intel-fixes 2015_02_01 commit 6b96d705f3cf435b0b8835b12c9742513c77fed6 with latest V55 BIOS, this issue does not exist.

Closing as NOTOURBUG. I don't think it pays off to bisect to find why the bios vesion matters. Ville, please reopen if you disagree. Closing old verified. |
