I have read through quite a few mailing lists and other sources but can't find an adequate solution. One solution I found was to turn off Local APIC support and IO-APIC support in the kernel, which I tried and it worked, but I'd rather not do this. I realise the error isn't of a huge concern but it's still annoying having it appear everytime the machine boots up.

Your fix is to just realize that this is a mere warning -- Nothing's wrong with your setup.
If you dig out a thread that came through here abt. two months ago, you'll find a comprehensive explanation of what the message means.
Fortunately... since kernel HZ changed to 1000Hz, I have about two these spurious interrupts delivered to the CPU on my A7V each second. Fortunately they are always really spurious, not misdelivered other interrupts, but seeing values like 10000 in ERR field in /proc/interrupts is something new to me ;-) Maybe VIA or AMD should really clarify what's the problem.
