State-Changed-Why:  
To submitter: is this panic recreatable, or is it a one-off? 
Often, panics in the amd64 pmap are traced to faulty hardware, 
is there any chance you can take the machine down and run (e.g.) 
Memtest86 on the machine overnight and see if that detects any 
issues?  Sadly, even if it passes that test, it's not a guarantee 
that the hardware is working fine, but if it fails memtest86 you 
can be sure the hardware is bad.

State-Changed-By: gavin 
State-Changed-When: Thu Nov 6 14:27:10 UTC 2008 
State-Changed-Why:  
Close, feedback timeout (2 months).  I suspect the cause to be 
faulty hardware, but without feedback there's nothing that can 
be done.
