Version-Release number of selected component (if applicable): kernel-smp-2.4.20-8 How reproducible: Didn't try Steps to Reproduce: Additional info:
please check the erratum kernel; at least something that could cause this is fixed there.
Sorry, I'm not familiar with RedHat; where can I find the changelog for the updates version?
I've been running the newer kernel package for over a month and it seems the problem is gone.
Created attachment 98527 [details] almost exact same oops.
This last oops is from 2.4.20-30.9smp, same shrike installation but moved to a P4/2.8GHz machine, HyperThreading turned off. Regards, Zoran
Thanks for the bug report. However, Red Hat no longer maintains this version of the product. Please upgrade to the latest version and open a new bug if the problem persists. The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, and if you believe this bug is interesting to them, please report the problem in the bug tracker at: http://bugzilla.fedora.us/
