QEMU/KVM Panic on USB Mount

[Sean Bruno]

In order to come up with the most convoluted problem possible, I present
to you screen shots of a panic from a FreeBSD VM running in QEMU
emulation under RedHat's KVM infrastructure.

I presented a perfectly functional USB partition from my host machine to
the VM.  Then I attempted to mount the partition from FreeBSD and it
generated the panics located here:

This is 100% reproducible.  But not an emergency or anything.
