I've seen a few cases of SM boxes across a few different CPU generations having issues with the BIOS defaults from the factory, especially when it comes to ACPI tables it creates... and a reset-to-defaults usually corrects the problem. I have no idea why their BIOS does this sometimes, being that it's a black box... but now I just automatically reset the BIOS on new servers if I ever run in to odd ACPI-related issues like this one on first boot.
