Subject: NFS regression?  Odd delays and lockups accessing an NFS export.

Hi there,

I've been using NFS here for years, lately there's something odd going on 
since about a month or so.  Previously reported last month:
http://www.gossamer-threads.com/lists/linux/kernel/951419?page=last

Now with 2.6.27-rc3 on one of the client boxes I get a complete stall 
at odd times when accessing the server's exported directory, cannot 
see a pattern to it.  Eventually recovers after a Ctrl-C.  Nothing in 
the server or client log files.  Not easy to reproduce either.

The server runs 2.6.26.2 at the moment.

Server config, etc: http://bugsplatter.id.au/kernel/boxen/deltree/
Client config, etc: http://bugsplatter.id.au/kernel/boxen/pooh/

Grant.
