It looks as if the response taken by the driver to this error (attempt to
reset the card) is guarenteed to hang the machine.  That's one issue - the
second is why you're getting the message in the first place.

I'm going to remove all the calls to drmRadeonEngineReset() from the driver &
see if there is better behaviour.
