[Ovmsdev] version 3.2.007: Crash on boot

[Greg D]

Odd.

Wonder which bus it was that it didn't have? I might try disabling the auto start of the obd2ecu task, and see if that changes things.  But that task doesn't transmit until it receives something from the device first.  Perhaps the first test would be to unplug the obdii dongle that's connected to the CAN3 bus, since it's the wildcard here, then work back from there.

The car is at Tesla right now, with them trying to determine once and for all the source of the 1146 alerts. ETA Friday...

Fingers crossed...
