That patch is probably what's missing then. Everything works fine here
now that I've turned of the 'Sense' channels. And there is no problem
retaining that value each reboot. The issue was that things stopped
working during the upgrade and the solution was far from obvious.

So I'm not having any problems with this change anymore. I was just
