[c-nsp] 12.2 -> 12.2S upgrade and PA-2T3+ problem

[Brian Feeny]

Tonight I upgraded a router that was running c7200-p-mz.122-26.bin to 
c7200-k91p-mz.122-25.S1.bin.
Before the upgrade one of its Serials was working fine, afterwards, its 
down/down.  The serial is a port
on a PA-T3+.  The other port is working fine.  I diffed the configs, 
and there were no changes that would cause operational problems.

I tried to reset the interface and still no go.  Its not a critical 
interface, so I havent reverted back to 12.2 just yet, I am going to 
try to figure out what happened here.  I did check "sh ip bgp sum" 
right before the reload after the code change, and that interface was 
definitely working.  Has anyone seen anything like this on 12.2S?
