Created attachment 154011 [details] dmesg with debug flag Since updating to 3.17.1, my Ivybridge graphics consistently crash upon boot leaving the screen black (monitor goes to standby) for a good 30 sec after booting. Attached is dmesg with the drm.debug=14 kernel parameter. I pulled out a few salient lines below. I am using the display port in order to drive my 2560x1440 monitor if that is relevant. My CPU is an Intel i7-3770k (Ivy) and I am using the integrated HD 4000 graphics together with the distro provided driver packages: intel-dri libva-intel-driver xf86-video-intel. Glad to provide additional logs/info upon request.

We seem to have neglected this bug a bit, apologies. Is this still a problem with recent kernels? ISTR we've fixed related issues, but can't find a specific commit.
No, running 3.18.4 without these problems. Probably safe to close.
(In reply to da_audiophile from comment #2) > No, running 3.18.4 without these problems. Probably safe to close. That's great. Thanks for the report and follow-up.
