I've solved my problem with changing the server because the previous server could not enable ACPI support. Moreover, I've succeeded in setting the host-ap up using ath(4). IMO, ACPI was a problem. I still encounter a panic during booting or ifconfig-up in the current server whenever I disable ACPI support. If I enable ACPI support, it works good.
