After a suspend I get messages such as these:

And if I was running X it crashes and the screen ends up looking like this:

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.
