excerpt from this list titled: NFS == lock && reboot, that I posted follows:

Greetings,
Does anyone know when NFS and friends will be working again? I haven't
been able
to /safely/ use it from 4.8 on. I remember some talk on the list
sometime ago and
then it seemed to be resolved, as the discussion ended. So I thought it was
fixed. Seems not. :(
My scenario;
mount host off root:
mount script exec'd follows...
#!/bin/sh -
mount -t nfs host.domain.tld:/ /host
mount -t nfs host.domain.tld:/var /host/var
confirm mount...
# ls /host
.snap COPYRIGHT bin
...
usr var tmp
OK looks good...
# cp /path/to/approx/10Mb/file /host/path/to/dest/dir/
Fatal double fault
eis 0x0blah
eiblah blah0x
panic double fault
no dump device defined
rebooting in 15sec...
Hmmm... that's not good. :(
------8<---SNIP---8<-----SNIP-----8<-------
My final solution was to change the lines in /etc/rc.conf
from:
nfs_client_enable="YES"
nfs_reserved_port_only="YES"
nfs_server_enable="YES"
rpc_lockd_enable="YES"
rpc_statd_enable="YES"
rpcbind_enable="YES"
to:
nfs_client_enable="YES"
nfs_reserved_port_only="YES"
nfs_server_enable="YES"
#rpc_lockd_enable="YES"
#rpc_statd_enable="YES"
rpcbind_enable="YES"
Making those changes ended the "Fatal double fault && reboot in 15
seconds..."
Thanks for this very timely mention! The cluster of servers I am
about to upgrade from 4.8 <embarrassed cough> to 6.2 relies heavily on
NFS to an old Netapp. If I have got to disable rpc_lockd and
rpc_statd, it's good to know that now!
Can I ask, can anybody confirm that they're running 6.2 on NFS
successfully *with* lockd and statd?
Er, yes, of course it does. The old message he is quoting is bogus on
its own, I don't know if he ever was able to provide meaningful traces
but it may well be nve as in the upthread discussion.
