c3k is a totally different chipset and MMIO mapping than
the C360 (original problem report).

We make no attempt to handle 64-bit ranges when running 32-bit kernel.
This is completely unrelated to the USB controller in (b).
This is probably the "PREFETCH Memory Range" of this Bridge not
getting allocated. Usually not a problem.

The ohci drive is really trying to say it could not allocate an MMIO region.
I'll submit a patch to linux-usb to make this clearer and see if they
shove it back at me impaled on a flaming spear. :) At least 7 different
USB drivers use this same (wrong IMHO) text.

ohci_hcd was attempting to load but failed and exited.
Note the reference count is 0 of both ohci and ehci USB drivers.
The driver load should have failed and should have unloaded.
But unloading manually might still work.

This looks like a bug in the generic PCI code.
This message is from drivers/pci/setup-res.c:pci_assign_resource():
...
min = (res->flags & IORESOURCE_IO) ? PCIBIOS_MIN_IO : PCIBIOS_MIN_MEM;
align = resource_alignment(res);
if (!align) {
dev_info(&dev->dev, "BAR %d: can't allocate resource (bogus "
"alignment) %pR flags %#lx\n",
resno, res, res->flags);
return -EINVAL;
}
...
kernel/resource.c:resource_alignment() returns 0 if neither
IORESOURCE_SIZEALIGN nor IORESOURCE_STARTALIGN flags are set.
Given "resource 8" is Bridge range and not a standard BAR, we shouldn't
be using the normal PCI range checking. Bridge ranges do not have the
same constraints on MMIO range allocation as normal BARs do.
I'm sure the PDC is doing the right thing in how it's allocating ranges.
The PCI code needs to handle the "Bridge Ranges" special. Just need
a stack trace of where this is getting called from and figure out
what to do differently. It's possible drivers/parisc/dino.c code
needs to change instead of drivers/pci code.

-16 == -EBUSY
This could be caused by 01:04.0 bridge not getting resources allocated
and ranges enabled properly.
