Alternate solution:
I've seen other boards where certain PCI addresses cause hangs. If you want to have full kernel PCI support, you might want to make a patch that lets you skip bad PCI addresses. i.e. some new kernel parameters like "badpci=foo,foo,...". In this case "badpci=0xa8".
This might be useful in the future.

I've seen this problem, but ONLY on VIA north bridges derived from the 8601. Hence I still blame the chipset. So we can build a working EPIA at this point?
Basically yes. If you have the above problem, you probably need to change the kernel to skip the pci probe.

it's not the pci address, that's the problem. it is a configuration space address. Will this commandline option let you skip config addresses?

Doh - I was not being clear. This was just an idea, to add a kernel parameter to allow skipping known bad PCI config space addresses. It does not currently exist until someone adds it.

It's not a bad idea, though, the xbox-linux folks have a similar problem AFAIK. We ought to combine efforts and try and get something into 2.5.
