While running some not-very-intensive upload tasks via samba (this
server being the recipient of the data), I got the following two oopses:

Examining the code in question, it looks like the serial key/keyring
tree is somehow corrupted, but it's not obvious how this happened or
where the race might be. There was _some_ file copying going on, as I
mentioned, but not a load situation I'd call anything more than trivial.
The system had to be rebooted after this, and the problem has not yet
recurred. It's a Dell Poweredge 1850 with 2 physical CPUs and HT enabled.
I looked around pretty extensively online for any similar bug reports
(vanilla kernel or debian), and found none, so I thought I should report
it. It doesn't look like any of the Debian patches touch the key code,
though. So this is probably upstream or broken hardware.
Any assistance appreciated, and anything I can do to help, I will.
Thanks in advance,
Matt Mitchell
