The motherboard has more than adequate cooling and is not touched and in a
proper cooled environment.
I do not recall seeing these in Kernel 2.6.3, although I am not 100%
certain.
Seriously, what would cause such APIC errors?

You stinker ;)
I replied to your email off list cuz I used to work with Al about 100 years ago in Utica NY.
I did trace the source of the kprint to the apic code. arch/i386/kernel/apic.c; smp_error_interrupt
0x40 is APIC error bit 6 "Illegal register addres" from the code comments.
The interrupt handler gets installed through some tricky BS code, see include/asm-i386/mach-arch/entry_arch.h using
a macro BUILD_INTERRUPT that insalls the error_interrupt by prefixing the "smp_" at compile time.
I'd say something strange is going on with some driver touching the APIC, but I'm no expert.
Can you reproduce it with 2.6.3 and the same .config used in your 2.6.4 version? (i.e both need to be running SMP or LOCAL_APIC kernels)

ummm, thats " 6: Received illegal vector " You have noise on your hardware.

These (40) report an incorrect interrupt vector. Do you ever see any
other values reported? If not, then I'd suspect an APIC configuration
error. There are a few debug facilities in arch/i386/kernel/io_apic.c
that can be used to investigate that.
