diff'ing the boot -v material for a good boot
vs. a failing one shows that . . .

Only the failure example has:

+module_register: cannot register simplebus/pcib from kernel; already loaded from kernel
+Module simplebus/pcib failed to register: 17

Only the good example later has:

-pcib0: <Generic PCI host controller> mem 0xf0000000-0xffffffff on simplebus0
-pcib0: parsing FDT for ECAM0:
-pcib0:  PCI addr: 0x0, CPU addr: 0xefff0000, Size: 0x10000
-pcib0:  PCI addr: 0x40000000, CPU addr: 0x40000000, Size: 0x80000000
-pcib0:  PCI addr: 0x100000000, CPU addr: 0x100000000, Size: 0x7f00000000
-pcib0:  PCI addr: 0x0, CPU addr: 0x0, Size: 0x0
-pcib0:  PCI addr: 0x0, CPU addr: 0x0, Size: 0x0

The failure example instead had:

+simplebus0: <pcie_at_f0000000> mem 0xf0000000-0xffffffff type pci compat pci-host-ecam-generic (no driver attached)

Later there was:

-usbus0: 5.0Gbps Super Speed USB v3.0
 Obsolete code will be removed soon: random(9) is the obsolete Park-Miller LCG from 1988
+usb_needs_explore_all: no devclass


I'll stop with that.
