I got this lovely bit of alphanumericism whilst trying to run xdm. 
 Anyone have any idea how to fix this bus error?

The first thing to do is run it through ksymoops to decode the numbers
to symbols.

As its an R5000 (from guessing) this is the random oops of the day 
due to the cacheing issues.

     Why is it called "common sense" when nobody seems to have any?
