IO-APIC not working on 645DX chipset??

IO-APIC not working on 645DX chipset??

[Allan Klinbail]

Hi 

I don't see that anyone else has experienced this. It may be just my
particular Motherboard Gigabyte GA-8ST667. (SiS 645DX chipset) 

If I compile a kernel with 
IO-APIC support on uniprocessors , enabled.then, the system succesfully
loads up modules for USB, ethernet card,scsi card, soundcards e.t.c..
but they don't actually work... 

I found turning this off then allowed everything to work again. 

I couldn't find (or know where to look) for information that confirmed
what was happening. 

cheers

2.4.x doesn't have work arounds for the SIS io-apic problems. SiS have 
told us what they are so there is a sort of workaround in 2.5. For 2.4.x
I'm still waiting for a list of afflicted devices from them so I can do
a safe minimal workaround to feed to Marcelo.
