Kernel Panic

[Kyle Butt <kylebutt@xxxxxxxxx>]

I have a repeatable kernel panic from a msdos rename. I have the
kernel core file and the kernel if You'd like me to post them
somewhere.

I have a usb hard drive based mp3 player that shows up as a umass, and
I was renaming the folder ebooks to TEXT when this happened. That's
all I have to do to repeat it.

Here is the back trace from gdb:
