IO-APIC IRQ setting fails: VT8235 - Sth Bridge / VT 400 - Nth Bridge

Hi,

I have opserved that the current linux 2.6test7 totally fails to correctly set the IO-APIC IRQs. Even in just PIC mode, it cannot change and IRQs. It just has to stay with whatever the bios set.

I attach output from the serial console during boot.

Can anyone give me a URL for the VT8235/VT400 chipsets, so that I could implement correct IO-APIC settting for Motherboards based on this.

Cheers
James
