<3>[ 41.685486] nouveau E[ DRM] GPU lockup - switching to software fbcon
And if I was running X it crashes and the screen ends up looking like this: http://imgur.com/a/D3VKw
This is always reproducible but only since Linux 3.15, so I ran a git bisect. The first bad commit is [ecf24de071f4f6cea79ecef5d990794df5875ee1] drm/nouveau: fix fbcon not being accelerated after suspend. After reverting the commmit the machine resumes properly.
The issue persists in drm-nouveau-next (last commit 0b4e8e7... from Jul 8), even if I boot with noaccel=1 nofbaccel=1.
