Here's a patch for those who have been plagued by APIC errors starting around 
-rc1-ac6.  I've submitted it to Alan, but since it has been affecting a 
number of folks, I'm also posting it here for your consideration and review.

This fixes the APIC receive accept errors on the two machines we have that 
were subject to it.  Let me know if it doesn't work for you.
