What kernel version - and below by stock I assume you really mean "Vendor
Patched" kernel?

Is your system BIOS fully MP 1.4 compliant? If you have a choice of MP
versions try setting the version to 1.4 (assuming a 'true' stock kernel)
and then seeing. If you still get the errors then try 1.1 - if the errors
go away with 1.1 bummer as that would imply you have a single APIC vector
table. 8-{

What settings - and 'stock' = ????
