Thus there is no debugging output. If it was acpi.ko, it would be labeled "elf module" as below: > Preloaded elf module "/boot/kernel/acpi.ko" at 0xc0a6127c. ^^^^^^^^^^^^^^^^^^^ Since the kld was not the kernel module, your kernel went and loaded the original acpi.ko from /boot/kernel, which doesn't have debugging enabled.
