--- Comment #5 from John F. Carr <[email protected]> --- If I boot verbose I see atrtc: atrtc-1 already exists; skipping it This message comes from devclass_alloc_unit. printf("%s: %s%d already exists; skipping it\n", dc->name, dc->name, *unitp); So *unitp == -1. Variable int unit = *unitp; was initialized to -1, or DEVICE_UNIT_ANY. So this BUS_HINT_DEVICE_UNIT call must have happened. /* Ask the parent bus if it wants to wire this device. */ if (unit == DEVICE_UNIT_ANY) BUS_HINT_DEVICE_UNIT(device_get_parent(dev), dev, dc->name, &unit); The printf is guarded by if (unit != DEVICE_UNIT_ANY) so BUS_HINT_DEVICE_UNIT must have assigned a unit number. This macro invokes a bus_hint_device_unit method. There are only three of these, one each for isa, pci, and acpica. -- You are receiving this mail because: You are the assignee for the bug.
