Title:
  NFS client hangs after some usage

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  We have an Ubuntu 10.04 machine.  I mounts a directory (statically,
  i.e. a line in /etc/fstab) on an NFS server.

  After some usage, the mount will simply hang. Any attempt to access
  the mount (e.g. ls /somedir) will just hang, and will have to be kill
  -9'ed.

  Trying to mount another NFS export on the same server, or another
  server, will simply fail (syscall failed). Trying to access the hung
  export from another machine works fine (i.e. the server side works,
  this is a client-side problem).

  This is kernel 2.6.32-45-server.

  What logs would you like? When trying to do this:

  rpcdebug -m nfs -s all

  All I see on an access attempt is:

  Apr 17 10:47:53 brent kernel: [145406.995318] NFS: revalidating (0:15/2)
  Apr 17 10:47:53 brent kernel: [145406.995326] NFS call  getattr

  If I do this:

  rpcdebug - m rpc -s all

  I get waaaaay too much info. :)  This box also serves as an NFS
  server, but when this glitch happens, the NFS server is unaffected.

  We cannot do upstream testing. We tried the latest kernel on another
  machine with the exact same config, and one of our network interfaces
  would not come up.
