Created attachment 114659 [details] Unedited console info. Thanks....
machine check exceptions are usually a sign of hardware going bad. Try running memtest for a few hours.
Created attachment 114680 [details] Second console capture... After eight hours of memtest. Another panic
Mass update of -test bugs to update version to fc4. (Please retest on final release, and report results if you have not already done so). Thanks.
Reproduced on FC4 released Note that the system will run with ide=nodma
Created attachment 116292 [details] ttyS0/console capture of the error
[This comment has been added as a mass update for all FC4 kernel bugs. If you have migrated this bug from an FC3 bug today, ignore this comment.] Please retest your problem with todays 2.6.12-1.1398_FC4 update. If your problem involved being unable to boot, or some hardware not being detected correctly, please make sure your /etc/modprobe.conf is correct *BEFORE* installing any kernel updates. If in doubt, you can recreate this file using.. mv /etc/sysconfig/hwconf /etc/sysconfig/hwconf.bak mv /etc/modprobe.conf /etc/modprobe.conf.bak kudzu Thank you.
softlockup disabled in latest errata.
