We really only want it set for pseries because of the > hypervisor being a PITA :-) Well, we did have some hypervisor work done at PA Semi too, and chances are it's from there. But it's unlikely since I think we booted pseries (PAPR) kernels under rHype. I suspect we just went with it for whatever legacy reasons and didn't revisit later -- since our firmware enumerated busses reliably there was no reason to redo it from the kernel. I've booted a system with pci_probe_only off here, and it seems happy enough. I'll send you a patch. Bjorn, that means you can drop this chunk of the patch, I suppose. -Olof -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
