Moving to Linux; this is a drm problem.

This is fixed upstream, and should be in linux 3.2; Ben Skeggs has given
me a list of the list of 13(!) (invasive!) commits that should fix this,
but given kernel freeze is two days away this might not be appropriate
for Oneiric.

Once git.kernel.org is back up I'll ask the kernel team to update the
drm-next kernel build so you can check that it's actually fixed there.

** Package changed: mesa (Ubuntu) => linux (Ubuntu)

Bug description:
  When plugging-in an external monitor on my MacBookAir3,1 using a Mini
  DisplayPort to DVI adapter my system freezes for a few seconds (screen
  doesn't update, can't type or move mouse, etc.) and the following
  errors are generated:

  For as long as I keep the external monitor plugged-in the intermittent
  freezes and errors continue. In System Settings -> Displays clicking
  Detect Displays doesn't detect the external monitor.

  System recovers and acts normally when I unplug the external monitor.
  I had been using this monitor just fine daily for months with Natty
  and the nvidia proprietary drivers.
