I really appreciate it. No problem, I think it's good to debug things to improve FreeBSD even if it's not my area of expertise. >>ACPI does not affect ATA other than setting up IO ports and IRQs.

I'm definitely willing to look into anything that acpi is screwing up if someone can point to the before/after behavior, I just can't spend more time in the internals of ata. -- Nate
