[cisco-nas] NVRAM problem

 From a case survey, this is almost surely an NVRAM hardware problem.  I 
had said "flash" because I was mistakenly thinking that on the 5350, 
NVRAM is part of main flash, but in fact it's a separate 512KB card on 
the motherboard.  I believe the NVRAM is soldered on the mainboard, so 
the FRU would be the chassis.

I suppose you could just load the config from TFTP instead.
