[nsp] 7507 reload entering in ATM commands on subinterface?

Hey guys,

I'm pretty sure this is a bug, but just wanted to throw this our there and see what
feedback was presented. I've done some investigation, but can't come up with anything
conclusive.

Basically an Access Router of mine reloaded when entering in pretty simple
ATM commands. The reload did not occur on another Access Router with the
exact same set up.

commands prior to reload:
------------------------------
conf t
  int atm5/1/0.1
  pvc 32/100
  nbr-nrt 128 64 128
-------------------------------

sh ver shows reason for reload:
"System returns to ROM by Bus error at Pc 0x601F3478,
 address 0x99c"

Using the memory maps 0x99c does not fall into any of the
areas of the memory map.
------------------ show region ------------------
Region Manager:

I have seen where a router reloads when you are making
changes to an interface that is passing traffic at that time,
but this was the first subinterface configuration for this atm card.
I'm sure this was a software forced crash, but the funny thing is that
when the commands were entred into an exact duplicate Access Router
no reload occurred.

-No related 12.1(4) caveats could be found.
-SPECS:
  7507 router w/ IOS 12.1(4)
  RSP4 w/ RISC processor 5000
  No slave in slot 3

-Router runs: ATM, PPP, BGP, SNMP
-ATM card: ATM DS-3 card (HW rev 2.00)
-Vip 2 controller (HW rev 2.11)

Here is an exerpt from the 'sh tech' of what it was thinking right before the reload.

"Queued messages:
  Sep 21 13:09:53: %SYS-3-LOGGER_FLUSHING: System pausing to
  ensure console debugging output.

  Sep 21 13:09:52: %SYS-5-CONFIG_I: Configured from console by
  jstorms on vty0 (172.18.244.92)
  Sep 21 13:09:53: %SYS-3-LOGGER_FLUSHED: System was paused
  for 00:00:00 to ensure console debugging output."

any insight would be greatly appreciated. I've opened up a Cisco TAC case, but
this has not been very helpful at all as Cisco wants to push this off on what I think
is an unrelated bug or upgrade my IOS for all my Access Routers on my network.

thanks in advance,

James
