I see this a LOT with USB drives. I had so many problems with it that I
moved all my USB drive enclosures to a dedicated box.

I've done a few things that seem to have helped:

    1. Upgrading to kernel-image >= 2.6.10 on the host server.
    2. Mounting the exported partition synchronously.
    3. Explicitly setting the export as synchronous.

The server still occasionally needs rebooting, but the client can
usually be fixed with a simple remount to refresh the stale NFS file

Hope this helps.
