Troubleshooting Bus Error Crashes on 68000 Processor Platforms With the address accessed by the router when the bus error occurred, use the show region command to determine the memory location the Guest One of my Cisco 3640 routers keep crashing lately, giving the following on the console-- -Traceback= 610561EC 610688F4 610484D4 *** System received a Bus Error exception *** signal= 0xa, code= based on MAC address -- why not "based on MAC addresses"? breakfast availability in Japan?

If this problem occurs, error messages similar to these are logged: %VIP2 R5K-1-MSG: slot0 System reloaded by a Bus Error exception %VIP2 R5K-1-MSG: slot0 caller=0x600BC974 %VIP2 R5K-1-MSG: slot0 System exception: sig=10, It is possible for CPUs to support this, but this functionality is rarely required directly at the machine code level, thus CPU designers normally avoid implementing it and instead issue bus Jason Kajita Follow me onTwitter http://support.microchip.com for urgent questions #2 aschen0866 Super Member Total Posts : 4035 Reward points : 0 Joined: 2006/01/08 22:18:32Location: San Diego Status: offline RE: Bus Error Another thing that you might want to check is the IPL specifier in your interrupt service routines.

Bus Error Linux

If the address reported by the bus error does not fall within the ranges displayed in the show region output, this means that the router tried to access an address that Ford,William R. It seems to have something to do with running Core Timer interrupt and DMA transfer completion interrupt at the same time. If you cannot access the Case Query Tool, you can attach the relevant information to your case by sending it to [email protected] with your case number in the subject line of

  • Also, please explain, is it a bad idea to a data type conversion for pointers.
  • Look carefully at the code above.
  • Troubleshooting Bus Error Crashes on RISC Processor Platforms It is recommended that you read the section on Troubleshooting Bus Error Crashes on 68000 Processor Platforms before you proceed with this section.

Verify, also, that the bootflash image supports the hardware installed if you have a router that supports a boot image such as the Cisco 7200 or Cisco 7500 series router. You really should get a minimal support contract ( 8 x 5 NBD ) so you can upgrade the software has anything changed in your environment lately in terms of volume In modern use on most architectures these are much rarer than segmentation faults, which occur primarily due to memory access violations: problems in the logical address or permissions.

The information in this document was created from the devices in a specific lab environment. After this, the router reloads. All rights reserved. If this problem occurs, error messages similar to these are logged in the show context output: Router#show context ...

Software Failure On 2600 and 3600 routers, the router's I/O memory is configurable as a percentage of the main memory. Bus Error Python For instance: unsigned char data[6]; (unsigned int *) (data + 2) = 0xdeadf00d; This snippet tries to write the 32-bit integer value 0xdeadf00d to an address that is (most likely) not The PC value is the location of the instruction which the processor was executing when the bus error occured. If you have the output of a show stacks or show technical-support (from enable mode) command from your Cisco device, you can use Cisco CLI Analyzer to display potential issues and

How far did you get in the assignment, and whatchange did you make to the kernel before you started getting this error?If you haven't looked a this already, it says it Bus Error Vs Segmentation Fault Printing the low order bits of the address shows that it is not aligned to a word boundary ("dword" using x86 terminology). Is there some way to catch this exception and continue loading my driver?

This worked well in one thread, but when using openMP this drives to bus error, because Mac OS X has very limited stack size for non-main threads.

Router platforms that have RISC processors include: Cisco 3600 Series Routers Cisco 4500 Series Routers Cisco 4700 Series Routers Route Switch Processor (RSP) Modules on Cisco 7500 Series and Cisco 7000 Similarly, if multi-byte accesses must be 32-bit aligned, addresses 0, 4, 8, 12, and so on would be considered aligned and therefore accessible, and all addresses in between would be considered However, the problem doesn't happen on every Explorer-16 board (with PIC32MX795F512L PIM) that I have. Verify that your configuration is supported in the Cisco IOS software and by the hardware.

The second thing to do is determine the type of processor in the router. Forgot your Username?

The one that's having issues does have an ATM interface that's connected via DS3 to a disaster recovery site. When there's only one person who knows how to do something crucial to a particular workflow, and that person suddenly becomes unavailable (i.e., "falls under a bus" - but most likely It's not so much type conversion as you're doing type conversion on a pointer that you've done pointer math on. Some systems may have a hybrid of these depending on the architecture being used.

As mentioned earlier, "main" corresponds to the main memory or the DRAM, so the DRAM chips need to be checked. share|improve this answer answered May 8 at 6:04 brucellino 1057 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up share|improve this answer answered Nov 19 '15 at 13:56 Alleo 1,3361422 add a comment| up vote 0 down vote This could refer to human problems too.
