A decoded version of the oops if a good starting point. It may be that 
your device is not properly supported, but thats no excuse for an oops. 
(unless the hardware is buggy)

The blinking keyboard leds indicates a panic. Whatever bug caused the oops 
went on to do more damage basically. (I'm sure others can elaborate / 
correct me on this)

Did the BUG message give a line number for iops.c?
