It could be that the MP BIOS routing tables aren't quite right. You
might want to try configuring MP interrupts using ACPI. To do that:

	* remove the MPBIOS options
	* add the MPACPI option
	* "acpi0 at mainbus?" to your config file.

Then re-config and recompile.

Beware, the mp acpi code isn't stable yet, so it may not work for you,
but it's worth a shot.
