Hi Aleksander,

Did you got a chance to see those logs? Please let me know if any other information is needed.

Hi Aleksander,

The crash was actually when mbim-proxy runs with --verbose. I applied your patch to fix it and attached are the requested logs.

Thanks
Amol

Hey,

This looks like QMI over MBIM indications not working properly, how strange.

Could you retry debug logging but also including mbim-proxy logs? E.g.:

// stop ModemManager and make sure mbim-proxy is not running $ sudo /usr/libexec/mbim-proxy --verbose --no-exit // in another terminal, start ModemManager in debug mode
