I think that rather than blaming the cpu, the motherboard could be the culprit. the "nodma" option actually had me running around for about 4-5 months earlier last year just because i was furious with the simple issue that win9x worked flawlessly and my simple 2.4.x kernels just wouldnt work. note: the 2.4.x kernels also used to show similar (but not exact) symptoms... the system used to reboot automatically while the kernel bootup was in progress (albeit, the automatic reboot used to take place while initializing the hard disks... precisely speaking it used to reboot while checking for partitions, or sometimes simply while checking for any ides available..)) the "ide=nodma" option helped there, and have been working in all later 2.4.x kernels... but a similar option for 2.5.x kernels dont seem to be doing the trick.. as far as the suggestions from dave are concerned, i have tried setting 1. cpu to 386 compatible 2. removing mce option but the problem still remains.. at the moment i am trying to remove *all* options which are not required for a simple kernel to function (eg. networking/ ). and trying it all over again... i'll send the new .config file over, if it works... affly robins
