hmmm. there's now a pcib2: <PCI-PCI bridge> at device 0.0 on pci1

and it actually does allocate memory, after the root fails to:

pcib1: rman_reserve_resource: start=0x670000000, end=0x67003ffff, count=0x40000
pcib1: pci_host_generic_core_alloc_resource FAIL: type=3, rid=28, start=0000000670000000, end=000000067003ffff, count=0000000000040000, flags=4800
pcib2: allocated memory range (0x70040000-0x7007ffff) for rid 1c of pci1:1:0:0

iiiinteresting. Try to kldload mpr/mps/whatever? Also insert the nvme drive
