QMI crashes when modem reboots during initialization

[Sai Chaitanya]

Hi all,

I am using libqmi APIs to enable data connection in my Sierra modem. I have
steps like these..

*qmi_device_new()*
*qmi_device_open()*
*qmi_device_allocate_client(dev, QMI_SERVICE_DMS, ....)*

*qmi_client_dms_swi_get_current_firmware*

*qmi_client_dms_get_operating_mode*

*qmi_device_allocate_client(dev, QMI_SERVICE_UIM, ....)*
*qmi_device_allocate_client(dev, QMI_SERVICE_WDS, ....)*
*----*
*-----*


My network manager crashes if the modem reboots for some reason, when the
initialization is in progress, somewhere in the middle of the above steps.

I am able to reproduce the issue very easily. All I have to do is to reboot
the modem with AT commands, while the above setup process is on-going in my
network manager.

Any inputs to fix this issue are highly appreciated.

My issue seems to be similar to this:

Kind regards,
Sai.
