ACPI is complaining because your BIOS is listing processors available

This is probably why. Some BIOS engineers aren't too bright.

Please file a bz on the non-booting case. It really should work.
Remove the 'quiet' option from the boot command line, and if possible
hook up a serial console and capture as much as you can.
