<pre>"failed to idle channel xxx" means "the gpu appears to not have hit a sync
point". This can happen for a variety of reasons, differing for different
hardware. It has a special propensity for showing up on a resume where
operations were going on while the gpu was suspending, but can also happen in
other circumstances.
I'm going to close this bug because the issue is reportedly fixed for the
original bug reporter, and every other commenter has vastly different hardware.
I would advise each of you to update your software (kernel, xf86-video-nouveau,
mesa) to the latest, and if problems persist file your own separate bugs,
indicate what hardware you have, and what steps to reproduce, including logs.
