>Environment:

NFS server is stock 2.2-960801-SNAP P-Pro 200 w/ AHA-2940 & 3G partition
Client is Solaris 2.5.1 on SS10

>Description:

Solaris defaults to using NFS V3. Aparently, so does this snapshot, since
I did nothing I know of in the kernel config to ask for it (options NFS,
FAILSAFE among others, but nothing about V3)

>How-To-Repeat:

solaris# mount -o rw,soft,bg,intr freebsd:/foo /mnt
solaris# cd /mnt
solaris# ls

At this point the FreeBSD machine panics with

ufs_ihashget: recursive lock not expected -- pid %d

Adding vers=2 to the -o list in the mount prevents this.
