Panic in ZFS layer on 8.1-STABLE

Hi,

[ Please Cc: me when replying, as I'm not subscribed to -stable@. ]

My filer at home runs FreeBSD.  A single data RAID-1 zpool with 10~15
datasets, two of them using compression.  Over the night, I got the
following panic:

fork_trampoline() at fork_trampoline+0x8       

I couldn't get a crash dump, sorry.  However, I'm still using the same
kernel so I can probably use addr2line(1) if you need it.
