fusefs broken on 8-stable?

[Johannes Totz]

Heya!

Using encfs (built on top of fuse) gives me panics in combination with
rsync. Dump didn't succeed. The info below is transcribbled from a
photograph. This is repeatable.
Without dump this is probably not very helpful....

First panic (top bits scrolled off screen):

Second panic:


code segment = base 0x0, limit 0xfffff, type 0x1b
             = DPL 0, pres 1, long 1, def32 0, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 17 (vnlru)

Any idea what could be going on?
