Bug Description
I have a Sierra EM7345 LTE modem in a Lenovo T450s.
On boot mbim-proxy is using 100% cpu and the modem will not move to the connected state.
I have to kill the mbim-proxy process to stop it using CPU, and I can't get the modem to connect at all.

The problem also occurs with Ubuntu 17.04 run from a live USB stick.
I've used this exact hardware with several previous installs of Ubuntu and never had this problem.

Note: this problem occurs on every boot up.
I tried upgrading to mainline kernel 4.12.10 and the problem still occurs.
Not sure if it matters: I was running Ubuntu previously on this hardware without this issue. I recently installed Windows 10 on this machine and successfully used the Sierra LTE modem from that OS. Then I installed Ubuntu and this problem happens every time.
Thanks for looking into it.
