msdosfs kernel panic

[Kyle Butt <kylebutt@xxxxxxxxx>]

This one is new to me. My System is running current as of
Apr 27. I have a kernel core in my home directory on leaf.

I was playing some oggs off of my windows drive, and I did
a find / -name "cf" when it crashed. Hope that helps. It
seems based on the back trace to be namecache related, but
I could be completely wrong.

Here's the backtrace:
