dmesg output, the error is near the end

The mentioned error is present in the dmesg log.

Possibly unrelated but at about the same time I was unable to switch from
console framebuffer back to Xorg VT (VT7). When I switch to X VT the system is
frozen for a few seconds (possibly just display+keyboard, dunno about I/O). No
X screen appears but the console text still visible. Then I can switch back to
the console VT. The X screen remains unaccessible but the X processes are still
running. A reboot has fixed the problem.

First few lines of xdpyinfo:

Is this still an issue with recent nouveau. We had a couple of Evo related
changes since reporting of this bug.

Please retest and come back to this bugreport. Thanks.

I'm closing this bug, since we have no retest from reporter for more than a
month and it seems nobody has similar problems with recent nouveau. If problem
persists please reopen with new logs.
