Nouveau - Jan 2015 - sys-kernel/gentoo-sources-3.17.7 - nouveau driver fails at system resume - nouveau E[ PGRAPH][0000:01:00.0] PGRAPH TLB flush idle timeout fail

Hello,

I'd like to bring to your attention a bug report[1] I have filed
on the Gentoo bugzilla about a regression (quite an old one) in
the nouveau driver.

If there is anything missing in the report that could help fixing
the problem, please feel free to ask.

Try booting with `nouveau.nofbaccel=1` and see if that helps. Some
many kernels ago, acceleration of the console on fb resume got fixed,
and is now causing issues for you and a few others. This will turn off
fbcon accel, which should hopefully sidestep the issue.

Hi,

It appears that in case of 3.17.7 as well as 3.19-rc2 the
nouveau.nofbaccel=1 helps. I don't get tons of "E[ PGRAPH]"
messages after resume and and the machine works OK in general.
