I thought I'd kick off a new thread with this announcement:

I do hope this turns out to be a weird software issue rather than a hardware problem even though extensive ground testing probably makes software bugs less likely.

I hope it's neither. I hope it was an uncorrectable, transient, radiation-induced error. What will be most interesting is how deep the safe mode is, and how graceful the failure is.

That wouldn't be too good, either. It would mean the spacecraft is too sensitive to random, unpredictable cosmic-ray events even while in the state of hibernation when most of the electronics are powered off. Imagine a trip like that during Pluto closest approach. I'd actually put those kinds of faults in the hardware "fault" category.
