From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7) Gecko/20040616 Description of problem: After running Seti@Home client (v3.08) for some time (not sure exactly how long, but it's less than 8hrs), the kernel comes across a kernel bug and kernel bug is output to console, but stack trace causes bug to re-occur, resulting in multiple reports of bug until stack overflow occurs. Eventually, kernel panics. Version-Release number of selected component (if applicable): 2.6.6-1.435.2.3 How reproducible: Always Steps to Reproduce: 1. Run Seti@Home v3.08 as non-root user. 2. Wait for a few hours (eg. overnight) Actual Results: Kernel panics. Expected Results: Kernel should not panic. Additional info: Hardware Environment: 1x(Intel Pentium III (Katmai) stepping 03); 256MB RAM; 1x4GB + 1x40GB IDE HDs (setup as 2 raid1 metadisks with no mirror, yet)
Any chance you can attach the console output, starting from the first BUG until the final panic? I personally like "netconsole" for this purpose (search Google) as an easy method of sending console output to another computer on my home network. Another option is netdump, but that is more difficult to configure. Are you sure it isn't happening due to overheating?
Created attachment 101862 [details] Entire output from kernel bug to kernel panic Attached text file shows the calls leading up to the stack overflow and a good number of messages before the kernel panics.
Not sure if overheating is an issue, but I doubt it, because I haven't changed the hardware config or physical location of this box for several months. But, this behavior distinctly started when I upgraded from RH9 (kernel 2.4.x) to FC2 (kernel 2.6.x). Only last night was I able to get around to configuring a serial console on the box, so that I could capture the output in the file that I attached above. So, I can't rule out overheating, for sure. But, I can say that the circumstances surrounding it seem to point to the kernel upgrade, rather than a sudden overheating issue. Seti@Home ran fine on the box before I upgraded to FC2 w/ the 2.6 kernel. Let me know if you still lean toward the overheating theory, and I'll try to come up with a way to monitor it.
Please try the latest rawhide kernels too.
interested to hear if this is still a problem with the 2.6.9 kernel update.
Fedora Core 2 has now reached end of life, and no further updates will be provided by Red Hat. The Fedora legacy project will be producing further kernel updates for security problems only. If this bug has not been fixed in the latest Fedora Core 2 update kernel, please try to reproduce it under Fedora Core 3, and reopen if necessary, changing the product version accordingly. Thank you.
