Problem Description:

I have nfs mounts mounted via automount. Suddenly it stopped working.
After short investigation, appeared that kernel helper thread stuck in 'D' state - refer attachement for "echo w > /proc/sysrq-trigger" output

Comment 2 Trond Myklebust 2008-05-30 11:24:12 UTC
This should already be fixed in 2.6.25, where rpciod is no longer
responsible for closing the open context, and therefore cannot get into
a situation where it calls rpc_shutdown_client on itself.
