[c-nsp] NPE-G1 with 12.2(25)S reload

Yes I opened TAC case 600966437


Initially, msimon at cisco.com thought it may be related to CSCdu58992.  I  
thought otherwise since:

a) CSCdu58992 was supposedly fixed prior to 12.2(25)S
b) CSCdu58992 applies to Intel based chipsets on the I/O Module, and  
mine has DEC based chipset

I downgraded to 12.2(18)S7, which is really where I want to be anyways,  
and I was still seeing the problem.

I think it MAY have been enviromental related.  The I/O module was  
logging warnings about heat
to the log.  107F it was it.

crashinfo_20050218-053551:17w2d: %ENVM-4-ENVWARN: I/O Cont Outlet  
measured at 42C/107F

Whats interesting, is that out of all the 7206's in that cabinet, this  
one has to coolest running NPE, which is an
NPE-G1.  Yet it had the hottest running I/O module, and not by a little  
either, by about 20 degrees!

The ONLY other changes I made, was I removed some basic policy maps  
that were put in place to do some LLQ
for voice traffic.  I plan to restore those policy maps here real soon.  
  I honestly think it may have been the heat issue.
Since removing some panels in that cabinet to make some better airflow,  
the I/O has been within tolerance, and I have
not had a crash yet.

I did not hear anything back from the DE who was looking over the  
crashlog however.
