It has been suggested that it is an IRQ conflict (or something > else related to APIC). I'll bet its interrupt routing more than IRQ conflicts (which these days on a modern system really doesn't make sense). More than likely there is some funkiness going on with the BIOS's ACPI tables (I would start with the MADT and verify its entries look kosher). Though it could be a power management problem and have nothing to do with interrupts (though with the SATA hard drives not being detected I would guess its interrupts). > Could someone please point me in the right direction so that I could try fix > this problem (i.e. how to change the IRQ of the ATA drivers or where to > fiddle with APIC to try get it to work?) I would read this: http://www.freebsd.org/doc/en/books/handbook/acpi-debug.html I would definitely set ACPI_DEBUG=1 and go from there. Perhaps if you can start dumping the AML on your system (acpidump) and any messages you get on the console (dmesg etc.) you can post them here. Also let us know what kind of BIOS options you have revolving ACPI, power management, and any legacy settings (e.g. MPS Table options if any). Without more information its hard to say what exactly is your problem other than disabling ACPI kinda fixes it. Also, PLEASE CHECK GIGABYTE's motherboard web page for any BIOS updates that have been released. Typically BIOS updates fix these kinds of problems. -aps
