From Bugzilla Helper: User-Agent: Mozilla/5.0 Galeon/1.2.6 (X11; Linux i686; U;) Gecko/20020830 Description of problem: I've been getting kernel oops with the message "Unable to handle kernel paging request at virtual address <address>". This is associated with crashes in X and gconfd. I'm attaching output from ksymoops. I have run all of Dell's hardware diagnostic tests (including memory tests) and have found no hardware errors. Nothing appears in the BIOS "event log" (such as overheating). I've run memtest86 overnight on this machine and it did not find anything. Version-Release number of selected component (if applicable): 2.4.18-27.8.0smp How reproducible: Sometimes Steps to Reproduce: Additional info:
Created attachment 90687 [details] Output of "ksymoops < /var/log/messages" immediately after reboot Last several oops in output resulted in X crashing, no keyboard input possible
I had an unexplained oops today on a single processor Athlon Thunderbird system running 2.4.18-27.8.0. I suspect this is related. Before upgrading to 2.4.18-27.8.0 the machine had been running fine for over a month worth of uptime.
Created attachment 90715 [details] More output from ksymoops This happened more or less simultaneously with my keyboard freezing. Not sure if they are related.
Created attachment 90815 [details] The saga continues... Definitely happens under load
Dell hardware diagnostic tests aren't very good, try memtest86 http://www.memtest86.com and cpuburn http://users.ev1.net/~redelm/
Been there, done that. I've run memtest86 overnight and cpuburn. Neither turned up any hardware errors. They might be there. I just couldn't find them. I'm going to do a fresh install of RH 9 and see if the problem persists.
