[rancid] odd cisco bug

[Jon Lewis]

Anyone seen this before?  We recently added a PA-FE to a 7206 running 
12.2(14)S19.  Every few runs, we get things like:

   !Slot 4: type 100BaseTX-ISL, 1 ports
   !Slot 4: hvers 1.4 rev B0
+ !Slot 4: hvers 1.4 rev B0
+ !Slot 4: part 73-1688-05, serial 22552957
   !Slot 4: part 73-1688-05, serial 22552957

and then

   !Slot 4: type 100BaseTX-ISL, 1 ports
   !Slot 4: hvers 1.4 rev B0
- !Slot 4: hvers 1.4 rev B0
- !Slot 4: part 73-1688-05, serial 22552957
   !Slot 4: part 73-1688-05, serial 22552957

i.e. the hvers and part lines keep having duplicate lines 
appear/disappear.  The card was online inserted, but the router has been 
rebooted since.
