Probably same bug as reported here? https://bugs.freedesktop.org/show_bug.cgi?id=89589
Yeah, looks so.
Though, the commit mentioned in the bugzilla is in 3.19-rc2, so this commit can't be the culprit.
I don't know, but wasn't it backporterd to stable 3.18 branch? I have tried kernel from yours repository, which is 3.18.6, not 3.18.0.
Good point! Indeed the commit was there through stable tree.
Is there other way to check it, other than install kernel 3.18.0?
You can revert the commit manually. This should be easily applicable even to the latest version. Just move the call of intel_dp_mst_resume(dev) in i915_drm_resume(). if the revert still works with 4.0 or 4.1 kernel, you can give the kernel messages with drm.debug=0x0e from both working and non-working cases to compare. -- You are receiving this mail because: You are on the CC list for the bug.
