You have been subscribed to a public bug:
In Ubuntu 24.04 on Panasonic Toughpad FZG2-3 with Sierra EM7595 the Sierra
modem seems to reset infinitely. I've found that running those 2 commands
succeed about 90% of the time:
sudo modprobe -r ucsi_acpi
sudo mbimcli -d /dev/cdc-wdm* --query-device-caps --no-close --verbose
Also checked on Ubuntu 22.04 - same issue but the issue is not fixed
after running the lines above.
I tried returning the module to the factory defaults, re-installing it's FW,
and changing multiple settings using AT commands.
I saw some issues in the dmesg and journalctl - see below.
Looking forward for your reply, Asaf.
