Hi
I am having trouble with a diskless system built from FreeBSD 2.2-961006-SNAP
There is a problem accessing subdirectories of NFS mounted systems.
If I boot the client single user and run
# set -x
HOME=/; export HOME
PATH=/sbin:/bin:/usr/sbin:/usr/bin
export PATH
swapon -a
mount -u -o rw /
umount -a
mount -a
. /etc/sysconfig
sh /etc/netstart
At this stage the network status seems OK
# arp -a
s5.elec.uq.edu.au (130.102.96.5) at 0:0:f8:2:3:d8
# ifconfig -a
ed0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 130.102.96.70 netmask 0xffffff00 broadcast 130.102.96.255

130.102.96.5:/export/clary on /
s5:/export/share on /share
s5:/usr on /usr
s5:/usr/local on /usr/local
procfs on /proc (local)
I can
ls / /share /usr /usr/local /proc
However any access of a subdirectory hangs the system.
For example,
chmod 666 /dev/tty[pqrs]*
ls /usr/bin
tcpdump at the server shows that it is hung trying to do a readdir

Can anyone suggest what might be causing this hangup?
