[Ovmsdev] Repeated WDT crashes after upgrade to 3.3 with 4G

[Jeff Anton]

I woke from sleep thinking "interrupt storm."

Craig's observation makes me wonder... Does the gps system produce 
interrupts which are not handled properly when gps is turned off. 
Unhandled interrupts might get constantly repeated causing the IDLE 
tasks to starve?
