Maybe you should look at supermicro site and upgrade bios. = I=20 think this is ACPI problem. You can disable ACPI temporarily at the boot=20 loader prompt by issueing "unset acpi_load" if you are having problems=20 booting an ACPI enabled machine.=20 =20 If you want to disable ACPI simply add hint.acpi.0.disabled=3D"1"=20 to /boot/device.hints.
