I applied Jim's patch. The good news is that it applies cleanly. The bad news is that it doesn't fix my problem. I does appear that there is a bogus value in the notifier die_chain. I put a dump_stack() in notifier_call_chain() and that is getting invoked from do_page_fault() so I am working under the assumption at the present time that I took an unhandled kernel page fault and the bogus value in the die_chain was causing the triple fault. Why the first of these happened is still a mystery. (2.6.11 without the kdb patches boots fine.) At the moment I'm trying to track down where the bogus value in the die_chain is coming from. -- Ray Bryant AMD Performance Labs Austin, Tx 512-602-0038 (o) 512-507-7807 (c) --------------------------- Use http://oss.sgi.com/ecartis to modify your settings or to unsubscribe.
