Help Troubleshooting Kernel Panic
Hi,
I am running Ubuntu x64 server edition. This has worked flawlessly for serveral years, however I have recently started to experience kernel crashes. Crashes seem to occur when downloading using hellanzb from news servers and only with large files (4GB+, though this varies. I updated from kernel 2.6.24-21 to 2.6.27-7 but problem stil exists.
It smells hardware related but only occurs wuth heavy downloads. I captured the output of the call trace and hardware info is attached. Any ideas on how to troubleshoot this issue?
I am relatively new at doing this.
Thank you!
