I've hit this using local disk while testing xfs built against 2.6.20-rc4 (SMP
x86_64)
dmesg follows, I'm not sure if anything in this is useful after the first event
as our automated tests continued on
after the failure.

Sorry I didnt pick this up ether.
I'll try to reproduce this and gather some more detailed info for a single
event.
