In fdc_initial_reset() shows here:
-----
fdc0: <Enhanced floppy controller> at port 0x3f7,0x3f0-0x3f5 irq 6 drq 2 on isa2
-----
Actual hang up is in loop in device_probe_and_attach().
With BUS_DEBUG, final output is here:
-----

This is called from isa_probe_children(), isa_assign_resources(i=40)
returns true, device_probe_and_attach().
Where should I check next? Inside of device_probe_child() or resouce
allocation area more ealier stage?
