The 'ignoring interrupt entry' message is very odd.  Can you get output 
from 'mptable'?  Are you able to boot with ACPI enabled?  At this point I 
would not be surprised if the MP Table was just flat wrong on modern machines 
as it seems many BIOS vendors do not test it anymore but only test the ACPI 
tables.
