This was happening on a 2621 running 12.1(5)T5 but I saw something
similar happen on a 2650 running 12.2(2)T.  I discovered that the cause
of the behavior was a speed change on the console port in the config. 
Somehow this was changing the config register settings and those changes
didn't always make much sense.  I changed the speed back to 9600 and the
config register was set back to 0x2102.

I haven't seen that before. What series of router is it? Could it be a
jumper setting?

Okay, what's the deal here?  Look at this output:

Configuration register is 0x2102 (will be 0x4000 at next reload)

RARAP#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
RARAP(config)#config-reg 0x2102
RARAP(config)#end
RARAP#sho ver
Cisco Internetwork Operating System Software 

[lotsa trimming]

Configuration register is 0x2102 (will be 0x3922 at next reload)

Why is the config register going to reload at 0x3922??  I just set the
darn thing to 0x2102 and you can see that change occurred.  I was
trying
to get rid of the 'will be 0x4000 at next reload'.  I have no idea why
that was there to begin with but it should not be there.  Is this
something that I'll have to fix from the console port?  I can't reload
the router because it was put into production this morning.  Why is it
set to 0x3922?  

I'm guessing that the guy who installed this was playing around with
the confreg utility in rommon and we'll have to go back to rommon to
fix
it.

Any ideas?

Thanks,
John
