It certainly has -- Housekeeping::Ticker1 increments monotonic and that 
isn't working. I had a look at the simcom power code and there is a 
vTaskDelay(1000 / portTICK_PERIOD_MS) in simcom::PowerCycle() but I'm 
not clear whether that is called when you power off the modem.

Would moar printfs to pin down where it dies help? I see the watchdog 
changes you've added, I'm not running them yet. I'll do that tomorrow.

Read that, tried a few things from it.

Is it possible to break into the system with gdb over the serial port 
and do a "thread apply all bt" or similar to get the state of all the 
threads? Or place a breakpoints in the right places and resume the system?
