It seems to boot reliably now (at least so far) but AC/DC detection is still iffy. Running from the docking connectors on back, It wants to stay on AC most of the time from a hard reset. If I tell Hijack to reboot for normal operation, it seems to detect correctly. Anything separate from this in Hijack that would prevent proper detection of power source?

Okay, at least now we're back to debugging the hardware again.

There's something *really noisy* on the tuner serial port signals. Maybe there's a short in/near the docking connector, or perhaps the line-driver chip for the tuner serial port is fried/flakey.

I think it's quite likely that the same problem is also what is causing the AC/DC detection to flake out. So there's two paths for investigation now, and hopefully they'll lead to a common component or two on the board (?).

It would be useful (again) to see the boot logs for both success and failure now.

Cheers
