Re: C7204 - bus error at PC 0x6083CAC0

See if router captured any crash dump in the flash?

#dir flash:

will list the files in the flash.

Capture the file and put it under output interpreture on the cisco web site it will give to the list of possible cause....

if u can not send it to cisco and they will send u the result.

I'm trying to access the Output Interpreter with the same username and password that i'm using with Netprof (CCO) but still can not login, is that it's requered special account??

Hi

The account is unique but u need to have special access permissions to use the tools like sotware advisor,output interpreter etc.,,

Mohamed the following is what I got from the transletor

ERROR: The system encounters a 'Bus Error' when the processor tries to access

a memory location that either does not exist (indicating a software issue) or does

not respond properly (indicating a hardware issue).

TRY THIS:

1. For 68000 Processor based platforms, carry out the following steps:

Consider the output:

"System restarted by bus error at PC 0x30EE546, address 0xBB4C4".

Here the system is trying to access the address "0xBB4C4"

a. Based on the address accessed by the router when the 'Bus Error' occurred,

use the "show region" command to determine the memory location to which

the address corresponds. If the address reported by the 'Bus Error' does

not fall within the ranges displayed in the show region output, it implies

that the router was trying to access an invalid address. This in turn indicates

a Cisco IOS Software problem. Use the Output Interpreter to decode the output

of the "show stacks" command to identify the software bug that is causing

the bus error.

b. If the address falls within one of the ranges in the "show region" output,

it implies that the router was accessing a valid memory location, but the

hardware corresponding to that address did not respond properly. This indicates

a hardware problem. Find the memory address that the system is trying to

access (for example in the above output, it is 0xBB4C4), and also the range

of memory addresses between which this address falls. The hardware issue

is most likely related to the corresponding component. If a new router has

been installed, or if the router has been moved from one location to another,

the memory chips may have become loose. It is recommended that you re-seat

or firmly push the memory chips into the slot.

For more information, see Troubleshooting Bus Error Crashes.

2. For the RISC Processor based platforms, use the Output Interpreter Tool to decode

the output of the "show stacks" command and identify the Cisco IOS Software

bug that is causing the bus error.
