Let me guess, you upgraded to 12.0.16.6(S) or higher from 15S or
below (13.5S also seems to do this)?
Almost every time we do that, the CSCs start 'dying' and we have
these problems. Cisco insists on having us RMA the CSCs, but it's just
as easy to fix this problem in software:
test mbus power X off (x == slot)
test mbus power X on.
Bounce the cards until they come up, then do an
upgrade all slot X, and in config mode, microcode reload the card.
Sometimes they'll stick again, but just bounce them until they come
back up. After that they are usually okay.
I have probably had to do this hundreds of times.
