这件事已经由Aleksander自己解决了。*邮寄名单上的摘要：

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?

有一次，似乎是MM挂起引导进程，因为一旦MM被删除，引导挂起也被删除。现在看来MM不是罪魁祸首！* ，我只想知道，MM是否有必要提供信息呢？

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.
