[Ovmsdev] Modem link-drop crash

[Greg D.]

Hi folks,

I left my module running with the modem connected (WiFi client off) for
a couple of days.  V2 server configured and connected, but the phone
client was not running.  The module was sitting on my desk (not in a
car), powered from the high-power USB port on my laptop.  It was
blinking happily last night when I went to bed, but dark this morning. 
Apparently had crashed and rebooted during the night. 

Here's the trace-back from the screen. Looks like a link drop was the
trigger, or perhaps the result of something else.

Hope this helps,

Greg
