Actually, for 5.3 it does. HEAD has the problem fixed, not sure about RELENG_5 yet, but due to the way IPIs are done in 5.3, having more than 2 CPUs can be very destabilizing, so disabling HTT on a 2-way system so that it goes from 4 CPUs to 2 CPUs can help stability very much. -- John Baldwin <[EMAIL PROTECTED]> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" = http://www.FreeBSD.org _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
