Unless this box has not adsl card on it, it might cause by hardward or software problem. Especially the interrupt type from the post is different from the the bug below. show context, show stack and show tech might help cisco finding the root cause.

Symptoms: A Cisco 2600 series may unexpectedly reload, or report "badshare"
tracebacks, or do both. When the router reloads, the router generates
messages similar to the following:


Unexpected exception to CPUvector 1200, PC = 818C8B80

-Traceback= 818C8B80 818C9454 818C9848 818CD814 818CA814 818C7A28 818BC7B4
801E64B8 801E5D30 801D9A44 804F8CBC 8047FD74 804EB824 804EB824 8047FE34
804EBCC0

When "badshare" tracebacks occur, the router generates messages similar to
the following:

%SYS-2-BADSHARE: Bad refcount in pak_enqueue, ptr=8316E0F8, count=0

-Traceback= 80406718 80407C38 818CC900 8026A9A0 80271EC4 8002258C 804FB374
804F8C84 8047FD74 804EB824 804EB824 8047FE34 80651388

%SYS-2-BADSHARE: Bad refcount in datagram_done, ptr=8316E0F8, count=0

-Traceback= 80403848 80407E68 818CC900 8026A9A0 80271EC4 8002258C 804FB374
804F8C84 8047FD74 804EB824 804EB824 8047FE34 80651388

%SYS-2-BADSHARE: Bad refcount in datagram_done, ptr=8316E0F8, count=0

Conditions: These symptoms are observed when the following two conditions
occur:

The Cisco 2600 series is configured with an asymmetric digital subscriber
line (ADSL) or symmetric high-bit rate digital subscriber line (SHDSL) WAN
interface card (WIC) that is installed in an onboard slot such as slot 0/0
or slot 0/1.

The upstream traffic rate exceeds the line rate, and this traffic is routed
through the ADSL or SHDSL WIC. (The line rate is the maximum speed allowed
by the digital subscriber line access multiplexer [DSLAM]).


Workaround: Do not use onboard slots.

Alternate workaround: Ensure that the router traffic rate is below the line
rate.

Hello All, I have seen many routers with an Unexpected Exception, like this one...

Unexpected exception to CPUvector 200, PC = 8002BD70

Free space check for flash:crashinfo_19930301-030756 failed (68/13152)

Is there something I can do (before opening a SR on the TAC) to know
what is really happening??
Thanks
Victor.
