It is likely that those aren't related. Mine K6-2/500, which I had while back, was also causing SIG 11, due to overheating. Another possible reason is memory - you should check that you have PC100, not PC66 installed, because K6-2/400 runs with 100MHz FSB. In this case, the possible overheating is eliminated by keeping the case fully opened but it doesn't help much. -Maxim To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
