From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0; T312461) Description of problem: I have had major stability problems after using up2date which installed a packet "kernel-2.4.9-21.athlon.rpm". I stepped back to "kernel-2.4.9- 13.athlon.rpm" which made the problems disappear. Stability: The kernel panicks oviously after some user program caused some file system access or the kernel itself wants to page. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. High base CPU load + any program causing file system access. 2. 3. Actual Results: Something like a "blue screen" appeared, mainly a stack trace. ... If the kernel itself was heavily concerned, "Aiee, killing daemon." and some message about failed sync attempts. Additional info: Excerpt from a log file.
