Still present in 3.13.2-gentoo. I found that -EBUSY returns from
nv50_fbcon_imageblit.

> what is wrong in nouveau's way of setting up pgraph.
Does it mean that the bug somewhere in nv50_grctx_generate? Just to be sure 
that bug in this function, is it possible to replace it using data from 
mmiotrace of nvidia driver? For me it is not obvious how to modificate 
nv50_grctx_fill in that case, what nv50_grctx_init should write to *size and, 
after all, may it help somehow?

Title:
  System hangs after some time with nouveau and GT240

Status in Accelerated Xorg driver for nVidia cards:
  Confirmed
Status in “xserver-xorg-video-nouveau” package in Ubuntu:
  Confirmed
Status in “xserver-xorg-video-nouveau” package in Fedora:
  Unknown

Bug description:
  With the Nouveau driver I get random system hangs in the Live CD - any
  version since it was switched to nouveau up until today's daily
  images. It happens after half an hour to a couple of hours usage and
  affects installed systems as well, until they are switched to the
  proprietary driver.

  This is a well known bug in other trackers but I can't see it anywhere
  on Launchpad, so I'm reporting it and will add bug watches.
