Sierra cellular modem keeps resetting

[Asaf Kampf]

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.

I found some error messages in dmesg:

it seems like removing the "cdc_mbim" kernel module fixes the issue
