Hi,
I'm having lots of problems with NFS deadlocks in my recent configuration.
Both client and server are 2.2-STABLE, with 3c905 100Mbps ethernet boards.
Right now, for example, I have a netscape and am elm locked. If this helps,
here's the output of a "ps -axlww | grep nfs" on the client:
zeus::jonny [501] ps -axlww | grep nfs

The relevant fstab options are as follows:
gaia:/ /gaia nfs rw,soft,intr,bg,nfsv2,dumbtimer 0 0
gaia:/usr /gaia/usr nfs rw,soft,intr,bg,nfsv2,dumbtimer 0 0
gaia:/var /gaia/var nfs rw,soft,intr,bg,nfsv2,dumbtimer 0 0
gaia:/extra /gaia/extra nfs rw,soft,intr,bg,nfsv2,dumbtimer 0 0
Using option "tcp" helps a lot, but if the server reboots, the client does
not reconect. "nfsv2" and "dumbtimer" seem to have helped, but did not
solve the problem.
Is there anything I can do to help debug this ?
Jonny
