nfs not reconnecting?

[Jonathan Noack]

Since upgrading to CURRENT a few weeks ago I've noticed my machine 
hanging when attempting to reboot.  The machine hits the watchdog 
timeout during the shutdown procedure because gkrellmd cannot be killed, 
prompts me to check out "ps -axl", and then hangs after syncing disks. 
I finally got around to checking it out and it appears some of the 
threads in gkrellmd are getting stuck in the nfsreq state.

The machine is an NFS client on a RELENG_5_4 NFS server.  I generally 
rebuild both machines at the same time for simplicity.  I then reboot 
the server.  Once the server is back up, I reboot the client.  When the 
client was running 5.x I saw "nfs server ... not responding" messages 
during the reboot of the server but as soon as it was back up I got "nfs 
server ... is alive again".  While running CURRENT I only see "not 
responding" messages (confirmed by no responses after the day I upgraded 
to "grep alive /var/log/messages" and "cat /var/log/messages.* | bunzip 
| grep alive").  I do occasionally see the message, "nfs/tcp clnt: Peer 
closed connection, tearing down TCP connection".

Does the NFS client not reconnect in CURRENT at this time?
