Please don't top post. You don't have to add things to the loader.conf file, you can manually do them at boot time with the "set" command at the loader prompt. My laptop used to boot fine without ACPI and now no longer boots without it. It hangs halfway through the boot sequence. I haven't had time to track it down. Some laptops cannot boot at all without ACPI. In the future, PC vendors will not make ACPI optional. I want the acpidump to look into the ATA irq routing warnings, not sure about the GPF you mentioned. Hopefully someone else can look at this. -Nate
