 Hi Joel,
 I've been exploring this a little further.
 I wonder if the actual bg scan task is stuck - even though scan
 start/end is being called correctly inside scan_task(), I wonder if
 something is trampling over the flags at the same time and causing
 scan_task() to think another scan is coming, but never does.
 A bgscan should be occuring every X seconds though. So I wonder why it
 wouldn't next be running.
 So would you mind plugging it back in and having it fail, then once it does:
 wlandebug +power +scan
 And then let's see if it actually _does_ try to do background scanning
 once it's hung. I hope it prints something useful about why it isn't
