Наблюдали сегодня такую же ситуацию, через 11 минут после загрузки модем отвалился и не поднялся. До этого момента он успел несколько раз “кувыркнуться”, пропадая и появляясь снова. Логи на момент фатального случая:

На сколько безопасно вызывать по крону wb-gsm restart_if_broken? устройства с новым модулем уже начали увозить на объекты, ситуация печальная. На 2g/3g по ppp у меня pppd долбил по кругу без остановок, каждый раз ресетя модем, это была довольно устойчивая к проблемам схема.
