We have 3 ASNs on the shelf that "fail CPU" test and that's it! The symptoms are consistant with an artical I found at Nortel:
"...units shipped between 5/95 and 2/97 are susceptible to a bit loss (transition from logical one to zero) in certain memory locations on the boot and diagnostic PROMs in these units. This occurs over time and a running system will not exhibit any symptom until a power cycle is initiated."
Anyone ever found away to 'fix' the prom via some other means or is a PROM swap/upgrade the only way?
