Try the appended patches and tell us if it works for you.

Currently, yes.  It shouldn't be.  Try running arlad with
`--fork-late' and tell us if that solves the problem.  (It should
probably be made the default behaviour.)

Can you find out (by running ktrace or reading the source) what
syscall the NetBSD libkafs is trying to use?  The xfs module will
install itself as syscall 210 if that's available and otherwise as the
first free slot reserved for LKMs.

Thanks.
