  nfsd from nfs-kernel-server very slow and system load from 25%-100%
  from nfsd

Bug description:
  I have a diskless ubuntu 10.10 machine which I boot regularly using
  pxe-boot from another ubuntu machine where I have the root filesystem
  of the diskless machine exported over nfs.

  I set it up about a year ago using 10.10. In the mean while the server
  machine got upgraded to 11.04 and as of yesterday to 11.10.

  After the upgrade to 11.10 the diskless machine is dead slow (most of
  the times it wont even boot completely) and the load on the server
  machine is high (25%-100% as shown from top). If in the middle of the
  diskless computer booting I do a restart of the nfs server, the client
  computer proceeds with the boot a bit more and then it gets stuck
  again. I have to restart and nfs-server 3-4 times in order to get the
  gdm login screen at the client machine
