This is exactly the problem that I see.

Me too :-(

On my 32bit "old" parisc machine 715/64 with GSC bus it still works.

But on all my PCI machines it fails the same way. Same result as Dave: pdc_add_valid() returns error.

For me it seems something has changed wrt PCI.

I tried to debug it somewhat, but I have no clue.
Maybe this commit is somewhat related: ?

parisc/PCI: get rid of device resource fixups
Tell the PCI core about host bridge address translation so it can take care of bus-to-resource conversion for us.
