Subject: Debugging hung tasks?

I am testing lots of NFS traffic against an over-loaded and slow file server.

I enabled the hung-task detection logic, and it's hitting after 180
seconds.

First:  Is there any valid reason to have funky NFS cause a hung task?

Second: Why doesn't the hung-task panic logic print the stack trace of
    the hung task?
    Is this an option that can be enabled?

Thanks,
Ben
