I had a similar panic on 5.0-R.  Do you happen to have any snapshots on any of 
the filesystems to which you might be writing at the time of the panic? I 
don't know how I determined it, but I found that the panic was the result of 
a snapshot on my /var filesystem.  Removing the snapshot solved the panic.
