    Commit:d6a9996e84ac4beb7713e9485f4563e100a9b03e (powerpc/mm:
    vmalloc abstraction in preparation for radix) turned kernel memory
    and IO addresses from #defined constants to variables initialised
    at runtime.

    On PA6T systems the setup_arch machine call initialises the onboard
    PCI-e root-ports, and uses pci_io_base to do this, which is now before
    its value has been set resulting in a panic right after 'booting
    linux via __start()'

I don't see the panic here on a Chitra, at least not on recent -next.

What config are you building with when you see this?

Please cc me on PA Semi related patches if you want my attention. I
still have hardware, in fact I boot every -next release on it through
automation.

You can find more details in the below thread.
