Hi Julian, This is a moot point about it being a kernel problem. It appears that the if the kernels does exactly as the ACPI configurations then we see the problem, however, telling the kernel to ignore the ACPI IRQ config we don't see the problem. This does not mean it's a kernel issue per sa, it means that the ACPI config is probably not quite right. The fact that Vista does it right may mean that Vista may ignore the ACPI IRQ routing much like when we tell the Linux kernel to do so by the acpi=noirq setting.
If you provide the output from: lspc -v cat /proc/interrupts from your machine booted in acpi=noirq configuration and also in the default configuration then I maybe able to see what is wrong with the BIOS ACPI IRQ routing and perhaps suggest a better workaround. However, these are workarounds for your BIOS ACPI settings, there is no kernel fix as this is not a kernel bug in my opinion.
