I haven't dug into the source yet today, but there must be a reason why ACPI doesn't play nice on certain systems when MAXMEM is specified. I wonder if it is just AMD systems? Mine's a 900MHz Duron, and IIRC I think someone else in earlier in the thread was using an AMD also. -- Eric Jones To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
