Fatal Trap 1: priviliged instruction fault while in kernel mode

[Willem Jan Withagen]

Instruction pointer: 0x8:0c021B8C0

And then the box was frozen solid....

The trap occured while compiling world over NFS V3/UDP.

With other Traps I've seen suggestions as to defective hardware.
Would this be in the same category, or would the Cyrix processor account for
this??

Thanx,
