Eric,
Do you try kexec with Nvidia ck804 based MB? it seems some one modify
the mptable but not update the checksum ...

The first kernel said:
..TIMER: vector=0x31 apic1=0 pin1=2 apic2=0 pin2=0
..MP-BIOS bug: 8254 timer not connected to IO-APIC
...trying to set up timer (IRQ0) through the 8259A ...
..... (found apic 0 pin 0) ...works.
testing the IO APIC.......................
.................................... done.
Using local APIC timer interrupts.
Detected 12.564 MHz APIC timer.
