If this is getting mis-routed (ie left floating) it might generate copious INTs. Try removing the network card, then boot. If you still get the INTs look at the pin 0 vs. pin 2 issue. If they go away it probably is something about the network card. Post the output of the 'mptable' program to the smp list. -- Steve Passe | powered by smp@csn.net | Symmetric MultiProcessor FreeBSD To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
