Description

I've just noticed something new with the way my System core is booting. (Alpha 10 OS)

It doesn't do it every time, but I've seen it a few times, and video'd it one time.

When I power on, the screen is blank for about 20 Sec, and then it goes through the normal spash creen sequence and gets to the normal status screen. But while it's starting up, the RED status LED on the SC is also flashing.
Once it's done this initial boot, it seems to immediatly do a second boot sequence, with the same splash screen again.

Looking at the video, it looks like the CAN bus does not start up the first time around.
The voltage from the Milwalkee battery say 16V. (it was charged yesterday).

It did it the first two times I powered it up today, but now it's not doing it.
I have a MotionCore attached with two A301's on ports 0 and 1
I also have the RHC2 installed.
