Hi,

It sounds like  it is having a Bus and Memory Management Unit  problem, 
according to this from princeton":
Bus Error
A bus error is issued to the processor when it references a location that 
cannot be accessed.

    * MMU: (Memory Management Unit: can be hardware or software, but frequently 
are system board problems.)
