hello list,

I just had a panic on a FreeBSD 9.0 built with yesterdays sources.

uname -a
FreeBSD  9.0-CURRENT FreeBSD 9.0-CURRENT #0: Sat Jun 26 09:14:30 CDT
2010     sfourman@:/usr/obj/usr/src/sys/ZFSv16  amd64

GENERIC kernel with this patch
i have a ufs2 boot drive with a separate ZFS pool

since this was a fresh install of 9-current(specifically to test the
v16 ZFS patches)

I was doing a zpool import of a 2TB dataset that has ~100 snapshots
it was taking over a hour to import, possibly this zfs bug

So I decided to build subversion from ports while I waited on zfs import
I got the panic in the following pics
