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....
# uname -a

First panic (top bits scrolled off screen):

Second panic:

processor eflags = interrupt enabled, resume, IOPL = 0
current process = 17 (vnlru)
trap number = 12
panic: page fault
cpuid = 0
KDB: stack backtrace

Any idea what could be going on?
