Ok, can you send me a full dmesg log with "debug" on the kernel command line after adding a #define DEBUG 1 to the top of drivers/pci/probe.c please ? (before the batch of #include). The generic code is _supposed_ to somewhat figure out that bridges haven't been setup by the firmware and fix that up, but for some reason it's not happening I think. Or something else is wrong ... Stefan, I could use the same log from your customer too. Thanks, Ben. _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
