Bug Description
network manager fails to establish a connection with the wwan on my lenovo x1 carbon.
I've disabled mbim using "options cdc_ncm prefer_mbim=0", so the driver indicated by network manager is cdc_acm.
When I try to make the connection, the process remains stuck at "Preparing to connect".
In the syslog I find the following (GSM connection failed: (32) Busy) :

Connecting with wvdial allows to establish a connection, as can be seen from the log below.
