온보드 Intel Wireless 7265(Dual Band Wireless-AC 7265)를 무시하도록 udev 규칙을 작성해 보십시오.

나는 성공하지 못한 채 udev에 대한 (몇 가지 다른) 규칙을 작성해 보았습니다.

KERNELS=="0000:02:00.0", ENV{ID_MM_DEVICE_IGNORE}="1"

규칙을 읽었지만 시작이 여전히 중단되므로 분명히 잘못된 것 같습니다.

알렉산더 자신이 이 문제를 해결했습니다. :) 메일링 리스트 요약:

Aleksander:

That is just an informative message. MM is not touching that interface for anything, it's just saying it cannot be used as part of a modem, as there is no control port. No udev rule to ignore the device will be hit, because MM is not even trying to use the device. That is definitely nothing to worry about.

Is MM really hanging the boot process? What exactly are you seeing? Any actual logs you can share?

한동안 MM이 부팅 프로세스를 중단한 것으로 나타났습니다. MM이 제거되면 부팅 중단도 제거되었기 때문입니다. 이제 MM은 범인이 아닌 것 같습니다! *
자, 그냥 알고 싶습니다. MM이 정보를 제공해야 합니까?

I think that message is not debug, and I agree that it may be a bit confusing to see it :D I'll see what I can do to silence those.
