Three "random" panics in two days....

From: Eric Schuele <e.schuele_at_computer.org>
Date: Sat, 01 Dec 2007 10:24:02 -0600
Hello,

Sending this to current_at_ since afaik 7.0 has not yet been officially
released?

I've had three panics in the last two days.  Oddly enough they have all
been while I'm at the office (as opposed to home).  The only difference
being a different wireless lan.

I have attached the three backtraces.  I've no idea if they are
enlightening in any way.  I was simply hoping 1) someone might comment
and point out anything that is wrong 2) maybe these could point to
something that should be fixed before release?

iirc, one happened on boot, one on shutdown, and one while my
screensaver was up.

If there is anything else I can provide please let me know.

Thoughts?

Eric
