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.
I wonder if this is what I've been seeing. I've been otherwise too
busy to properly report it, thinking that *someone* else must also be
seeing it and it's being worked on, else it's a subtle configuration
problem my end.
I first started seeing this with 2.6.26 on the client end,
I see you're running the atl1 driver on your client. I'm chasing an
intermittent bug in that driver that seems to be affected by certain
offload parameters. Try disabling TSO and see if things improve.
ethtool -K eth0 tso off
Let me know if it helps.
