Hmm, interesting, perhaps OFW is not setting things behind bridges up for u=
s?
But in short, pci_mapreg_map(9) is failing somehow.

I'd like to see the output of the debugging code near here. tlp_srom_debug
needs to be non-zero. (short pause while I go off to find the email
that explained how) Backup your kernel, then:

gdb --write $TEST_KERNEL
set tlp_srom_debug=3D1
quit

and then boot $TEST_KERNEL.

Something (hardware, firmware, kernel) is not handling the PCI bus
properly.

And why don't we see identical errors for all the tlp(4)s behind the
ppb(4)?
