I'm not sure if this is new to -mm3, but it's the first time I have seen it.

The sequence of events leading up to this was to reboot the machine, it came up
and crashed:

See the previous bug report about this one that I just posted in it's original
thread. I had to reset the box to clear that one.

After rebooting, now a new problem:

I reported a bug in November about SATA timing out in a similar fashion when
booted on an SMP kernel but with 'nosmp' on the kernel command line, it had
similar symptoms FWIW, and may or may not be something related.
