Subject: NFS slow to respond on resumption from hibernate

I've started hibernating some of our Fedora desktop machines. Problem is that
we have NFS mounted home (and some other) directories and access to these can be
*slow* (several minutes) to recover on resumption from hibernate. Other network
activity is fine. Fedora bug is here:

https://bugzilla.redhat.com/show_bug.cgi?id=510536

Any thoughts on what might be causing this or how to debug?

Thank you,

Orion

Start by upgrading to the very latest Fedora kernel, which is 2.6.30
based. There are a couple of RPC/tcp reconnection fixes there that
didn't make it into 2.6.29.
