Cellular Modem will not pass data after pfSense 21.02_1 upgrade

tose

I have an SG-3100 that has a Sierra Wireless EM7345 LTE modem installed to provide WAN failover in the event that the terrestrial WAN service is unavailable. It has operated fine on pfSense versions up to 2.4.5-p1. On upgrade to 21.02_1, the interface appears to initialise properly, shows it's up, has all it's addressing information as usual, but simply will not pass any data.

Previously on rare occasions that the modem had seemed to lock up I was able to use the following commands from the console to reset it:-

cu -l /dev/cuaU0

AT+CFUN=16

On attempt to do the same thing after upgrade to 21.02_1 I simply receive:-

All ports busy

Seems like the device is just locked up. Have done a bunch of googling to find anyone suffering similar issues in either pfSense 21.02 or FreeBSD 12 more broadly, without any luck. Hoping someone here might have seen similar issues or have some suggestions for further trouble-shooting.

Just adding output of console at boot time:-

I can't recall ever seeing the "Root mount waiting for: CAM" or "mountroot: waiting for device" output under pfSense 2.4.5-p1

Is it still at that com port?

The Root mount waiting for: CAM lines are expected in 21.02 and not a concern.

You are using the ue0 device to actually connect over I assume? It just doesn't dial out now?

Thanks for your interest. Responses attached. Sorry but it's the only way I could get it past the SPAM botreply.txt

Upvoted some of your posts, you have a +5 rep now you should be able to post.

I have one of those modems but I don't use it because it's always been a bit flaky for me.
The modem itself sometimes gets stuck in a boot loop causing it to appear and disappear.

If you're not using the ue0 interface I would recommend trying to use an em7305 or em7455 if you can. I'm currently using an em7305 in an SG-3100 here and it's been reliable. Speed is not huge but it's a backup.
