Thanks - I've looked over lba_driver_probe() and I'm wondering why
we are getting a NULL pointer back from pci_scan_bus_parented().

If you could determine why pci_create_bus() is returning a NULL
pointer to pci_scan_bus_parented(), that would probably provide
clues to the real problem.

And the first "if (lba_bus)" right after that bus scan seems
wrong to me too since the code below it will crash anyway.
Seems a NULL lba_bus should cleanup and exit with an error.

thanks,
grant
