(Output from dmesg is included below.) Thats fine, its due to the way io apertures for different host bridges are handled. The apertures are mapped in one after the other so that only the first one has no offset. If you have more than one host bridge, you have to add the offset since the io ports are all relative to the start of the first host bridge aperture. Anton ** Sent via the linuxppc-dev mail list.
