I have a TK1 connected to a modem that is handled by ModemManager and eventually pppd. The system usually operates as expected by booting, connecting to a network and remaining connected to a network until shutdown. In around 10% of the trials the network connection fails. This usually also causes most mmcli commands to hang. Inspecting dmesg given below reveals a kernel panic related to pppd. The error occurs at 725.097917

I have a TK1 connected to a modem that is handled by ModemManager and eventually pppd. The system usually operates as expected by booting, connecting to a network and remaining connected to a network until shutdown. In around 10% of the trials the network connection fails. This usually also causes most mmcli commands to hang. Inspecting dmesg given below reveals a kernel panic related to pppd. The error occurs at 725.097917
