Turns out this isn't the bug I was looking for....
However, I think this might be useful anyway so thought I would hand it over to the community just in case.
When trying to work out the cause of a brown-out recovery issue (think very low-battery situations) I spotted that there are some edge-case scenarios that could result in the board hanging on boot if the radio doesn't come online correctly. To work this out I ended up implementing a load of instrumentation as well as some routines that should prevent trivial lockups from occurring if the power rail isn't stable enough to support a radio init at boot time.
