Please try drm-intel-nightly branch of http://cgit.freedesktop.org/drm-intel Sadly that kernel doesn't boot at all - just an empty black screen. (In reply to Sitsofe Wheeler from comment #2) > Sadly that kernel doesn't boot at all - just an empty black screen. Meh. What if you cherry pick commit f9b61ff6bce9a44555324b29e593fdffc9a115bc Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Wed Jan 7 13:54:39 2015 +0100 drm/i915: Push vblank enable/disable past encoder->enable/disable on top of v3.19? Created attachment 113465 [details]
EeePC dmesg
f9b61ff6bce9a44555324b29e593fdffc9a115bc solves the drm_wait_one_vblank warning but check_crtc_state (pipe state doesn't match!) still remains. Do you want a separate bug for that?

Do > you want a separate bug for that? Sorry for the delay - yes please. I'll try to get the referenced commit backported to v3.19 stable kernels. New issue filed as #89209 . Feel free to close this issue as resolved when you're ready Jani! Thanks for the report.

and after that I tried a build with the merge of intel-drm-nightly like it was suggested in comment 13 on this bug https://bugzilla.kernel.org/show_bug.cgi?id=92171
(In reply to Christian Hartmann from comment #11) > still present in: > -> 3.19.5 and > -> 4.0.0 ... > [ 3.935536] WARNING: CPU: 3 PID: 262 at drivers/gpu/drm/drm_irq.c:1130 > drm_wait_one_vblank+0x177/0x180() > [ 3.935546] vblank wait timed out on crtc 0 Please observe that this is a different warning, and a different bug. Closing again. Please reopen if you see "vblank not available on crtc 0, ret=-22". Otherwise, please file a new bug. Or find another bug with your error message. Thank you. I experience the same issue on kernel 4.2-rc6. Before that I needed to boot with the i915.preliminary_hw_support=1 i915.enable_ips=0 kerne parameters, otherwise switching VTs was broken. Now switching works but I get the vblank issue and graphical artifacts. If you need more info or think this is a different bug, please state it so I can open another one. Also contact me if you need more info.
