After upgrading to nfs-utils-1.0.6-r6 the other day, my nfs-server started to experienced hard lockups (magic-SysRq fails -- hard reset or power cycle required) several minutes after any clients accessed an NFS share. Usually I was using Rhythmbox at the time. No useful information appeared to have been left in any log files after rebooting. After downgrading back to 1.0.6-r5 the lockups have stopped.

Argh, the lockups persist, just on a longer time scale, even if NFS is not mounted. I will have to figure out more what the root cause of this is.
