Description
My machine is equipped with two FM150 modules. However, from the source file's driver, I noticed that the Qualcomm X55 machine still uses Quectel's driver, which causes occasional module loss issues. The machine can only re-dial after a complete power-off. Can we update Quectel's original PCIe driver to better support the FM150? From the current symptoms, I can force restart the module through GPIO in the system, and the module can start normally. However, qmodem can no longer dial normally because the AT serial port is not working. So, I would like to know if there is a good way to solve this problem.

Research direction
The issue names no source files or tests. Start by locating the Quectel PCIe driver and qmodem's AT serial and GPIO-reset entry points, then reproduce the FM150 module-loss and redial failure; done means the module recovers without a full power-off and qmodem can use the AT port to dial normally.
