I did a couple of restarting ofonod and connmand during the debug, one or two times power recycling manually, not clear if it was me to cause those reboot or not. Like Daniel said, it was unlikely that connman would run reboot, it might just record some messages from kernel. Just talked to the hardware engineer, he said who is very concerning we are using kernel 5.1.0, he said we should use kernel 4.9.123, could the kernel 5.1.0 cause that issue? Jonas what is your comments? Let me further clarify it, the issue did not occur very often, it occurred randomly between hours to many days, that is a big worry, LTE should be 100% stable. Thank you.
