It's known. The last time I changed some of the code I tried to
minimize this, but it doesn't solve the problem yet. :-(

Here's my suspicions, everyone please let me know if you see
different:
1. Happens on II series hardware
2. May happen on IIsi series hardware
3. May not happen on Cuda series hardware
4. ADB activity before or during adbreinit causes the problem.
5. ADB activity after adbreinit should NOT exhibit the problem.

Turning interrupts off for ADB right from the start might help, but
I'm not sure how to do that safely without breaking other things.

I'll see what I can do.
