That's an oops caused by a consistency check while printing 
/proc/slabinfo. Probably a side effect of the first oops.

but no trace of the other one, which was deffinately a lockd process 
(nfs related afaik).  Oh well, thanks for the help.  At least this 
confirms (for me at least) that there is a problem in the server side 
nfs code.  And now I know about ksymoops.

There's a tool called ksymoops to decode the symbols.
You can find it on kernel.org

Hello all

The following OOPS occured this morning.  This is on a dual CPU machine, 
there were two oopses, unfortunately the other scrolled off the screen 
but the process was lockd (nfs related afaik).

Here is the oops (written off and typed up), unfortunately I don't know 
how to convert this to nicely readable symbols ...
