--- Comment #9 from Howard Powell <hpowell@lighthouseinstruments.com> ---
I've replicated this issue with a non-boot zfs filesystem on 10.3-RELEASE.

zpool create foo /dev/ada1
mkdir /foo/bar

zfs snapshot foo@working-copy
ls -d /foo/.zfs/snapshot/working-copy/bar
zfs destroy foo@working-copy

Output is=20
panic: vputx: negative ref cnt

followed by a dump and reboot.  I've uploaded the vmcore.txt that was gener=
ated
by this bug.
