[Bug 2036427] [NEW] Upgrade to version 249.11-0ubuntu3.10 breaks 12d1:15c1 Huawei ME906s LTE M.2 Module

[grufo]

Public bug reported:

Description:	Ubuntu 22.04.3 LTS
Release:	22.04

After the latest upgrade our Huawei LTE modem is not working anymore. 
We can see the modem wie lsusb, but no interfaces gets activated and systemd-networkd-wait-online gets a timeout.

The following packages have been upgraded:
Upgrade: udev:amd64 (249.11-0ubuntu3.9, 249.11-0ubuntu3.10), systemd-timesyncd:amd64 (249.11-0ubuntu3.9, 249.11-0ubuntu3.10), libpam-systemd:amd64 (249.11-0ubuntu3.9, 249.11-0ubuntu3.10), libsystemd0:amd64 (249.11-0ubuntu3.9, 249.11-0ubuntu3.10), libnss-systemd:amd64 (249.11-0ubuntu3.9, 249.11-0ubuntu3.10), systemd:amd64 (249.11-0ubuntu3.9, 249.11-0ubuntu3.10), libudev1:amd64 (249.11-0ubuntu3.9, 249.11-0ubuntu3.10), systemd-sysv:amd64 (249.11-0ubuntu3.9, 249.11-0ubuntu3.10), thermald:amd64 (2.4.9-1ubuntu0.3, 2.4.9-1ubuntu0.4)

When we switch back to an older version the modem is working again!

Downgrade: systemd-timesyncd:amd64 (249.11-0ubuntu3.10,
249.11-0ubuntu3.7), libpam-systemd:amd64 (249.11-0ubuntu3.10,
249.11-0ubuntu3.7), libsystemd0:amd64 (249.11-0ubuntu3.10,
249.11-0ubuntu3.7), libnss-systemd:amd64 (249.11-0ubuntu3.10,
249.11-0ubuntu3.7), systemd:amd64 (249.11-0ubuntu3.10,
249.11-0ubuntu3.7), systemd-sysv:amd64 (249.11-0ubuntu3.10,
249.11-0ubuntu3.7)

So the latest update breaks anything with that modem.

The output of lsusb stays the same with both versions:
Bus 001 Device 003: ID 12d1:15c1 Huawei Technologies Co., Ltd. ME906s LTE M.2 Module

With old packages "ip link" looks like that:
9: wwan0: <BROADCAST,MULTICAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UNKNOWN mode DEFAULT group default qlen 1000
    link/ether 2e:c4:ac:0a:11:f2 brd ff:ff:ff:ff:ff:ff

With new packages "ip link" does not show any wwan0 or similar interface.
Other network interfaces are avaiable.

We have a lot of systems with Huawei LTE modems and that's a serious problem for us!
Do you need more information to debug that problem?
