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.
