[Bug 532808] [NEW] [1266874884.391257] BUG: soft lockup - CPU

[Antonio]

Public bug reported:

I don't know exactly what is going wrong. A warning appears on the top
bar telling me there is a serious error.

 Moreover, and I don't know if it has something to do with that, on the
right-lower corner there is a "ATI Unsupported hardware" message.

The computer is since I installed ubuntu.
