Where might one find the list of trap_types and cpuerrs? On Mon, Jun 5, 2017 at 12:33 PM, Ron Natalie wrote: Trap type 0 is bus error. The two causes of this are either addressing memory location that does not respond (as opposed to being umapped) or an word operation on an odd address. Since you have a cpuerr print out you have a 44/45/70 CPU. The 020 value indicates that it was the bus timeout case. Something touched memory that was mapped in but didn't physically exist. -------------- next part -------------- An HTML attachment was scrubbed... URL:
