Modem turns off on suspend
#1
I recently upgraded to Tow-boot, and installed Arch with kernel 5.17. Suspend works fantastic, however every time the phone suspends the modem turns off. That's great for power saving, but defeats the purpose of having a phone. Is there a way to prevent the modem from turning off on suspend? Running Foss firmware 0.6.1 and I did change the udev rules as specified in the documentation for the firmware on Github. I'm honestly clueless what else I can do.

I can confirm for Mobian-FDE (Two-boot) and the 5.16 kernel.

Please explain what you can confirm, i.e., does the modem turn off in suspend or stay on to answer calls in suspend using Mobian-FDE.

I am incredibly confident the modem is turned off because it is flagged as unavailable upon resume and calls/sms can't be received until it wakes up and reenables itself. Switching to a different system, specifically Mobian (No FDE) resolved the issue for me.
