I have a machine that does this. My Dell Inspiron 8000. The reason that it does this is because the disk spinning down has nothing to do with APM. The BIOS tells the disk to spin down when it has been idle for 30s. When FreeBSD boots, it doesn't give orders to the contrary, so it still spins down when it has been idle for 30s, regardless of FreeBSD's APM or ACPI use. I've commented on how I think that it should be in other mail. Warner To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
