we have here a strange problem.
After Upgrade JunOS from 8.5 to 9.3 on our M20-Router the FPCs case errors
and go off-line.
Which kind of FPCs are these?
The very, very old FPC's (prior to E-FPC's) no longer work in 9.3, as
stated in release notes. This may or may not be related.
Enclosed is an excerpt from the logfile (/var/log/messages):
----
ssb CM(0): Slot 0: Unrecoverable error; probe failed

craftd[4431]: Major alarm set, Too many unrecoverable errors

Has anyone an idea what the reason might be?
