I just encountered an Oops on my IBM ThinkPad T21 with 2.6.0-test11. I
suspect that it has something to do with my battery being so low that it would
not even give a reading. I had to copy down the oops and by the time I
rebooted the machine, it had charged enough and booted successfuly. Here is
the text of the oops:
