thanks - that works!  dmesg at the end.

I've written down a bit more. the pci_make_tag arguments were

pci_make_tag(pci_chipset_tag_t pc = some pointer,
              int bus = 0,
              int device = 2,
              int function = ffff)

so it looks like it was the "function" that overflowed.
The rest of the stack was (with possible mistakes on my
side, these stack levels are all very similar so it's
easy to make mistakes writing them down on paper :-)

pci_make_tag

get_bus_number
