[j-nsp] M20 fpc issue

[Joe Freeman]

I started with a 10.0 train with the same symptoms.

show log chassisd only shows an snmp trap for fru removal when the fpc is
trying to come up.

show log messages has this, though-
Oct 15 13:56:48  lab-m20 alarmd[1532]: Alarm set: FPC color=RED,
class=CHASSIS, reason=Too many unrecoverable errors

Oct 15 13:56:48  lab-m20 CM(0): Slot 3: Unrecoverable error; probe failed

Oct 15 13:56:48  lab-m20 CM(0): ALARM SET: (Major) Slot 3: Too many

So no real clue as to why it won't come up. Again, I get this on every FPC
I try in the box, and I've tried a different chassis (using the same re's)
with the same results. I initially thought it might be an expired hardware
certificate on the FPC, but setting the date back to 2001 didn't help.
