Modem not resetting.

Hi, I see an issue when resetting modems, both with Telit and Sierra. It
happens quite rarely but renders the modem unusable. I tell the modem to go
offline and then to reset, most of the time this works, it's a standard
thing. Occasionally it will say that it is a success but never actually
reload, no matter how many times you issue the commands after this the
modem won't reset, and it also can not come back online (invalid transition
I assume). Here is the verbose output if that helps in any way, any test
you thinkI can run while I have a modem in this state? (Telit LNM960A18)
