Public bug reported:
Binary package hint: linux-image-2.6.38-7-generic
I'm using the current Natty dev version since yesterday and already had
several kernel BUGs, apparently related to my DVI-attached external
monitor:

Once this happened when unplugging the DVI plug, once or twice this
happened without any (apparent) intervention by me.
I also get the following messages from time to time, after which both
the external monitor and my laptop's internal display get blank for a
short time, before the external monitor is re-detected and re-activated.
I'v not seen any of these problems before.

The external display in question is an about two month old Ilyama
ProLite B2409HDS TFT panel.
I'm happy any additional information required to hunt down this bug.
