Title:
Upgrade to version 249.11-0ubuntu3.10 breaks 12d1:15c1 Huawei ME906s
LTE M.2 Module
Status in systemd package in Ubuntu:
Confirmed
Bug description:
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.
The network interfaces are configured with /etc/network/interfaces:
allow-hotplug wwan0
iface wwan0 inet dhcp
apn a1.net
metric 100
We use modemmanager to connect:
/usr/bin/mmcli --modem 0 --simple-connect="apn=a1.net"
"mmcli -L" can't find any modems on a upgraded system.
With the previous version we see the Huawei modem:
/org/freedesktop/ModemManager1/Modem/0 [Huawei Technologies Co., Ltd.]
HUAWEI Mobile V7R11
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?
