My data point
Fire tablet, wouldn't charge or for that matter even turn on.
Apparently related because it seems to have happened during a routine update and the unit refused to do anything until charged a different way to usual (ie through external power not the provided USB-micro adaptor)
So for those reading this, plugging it into the mains is a wise idea BEFORE enabling 3G and ideally ensure it is at 100% SoC if it shows any sign of updating.
Apparently if it gets below 50% bad things (tm) can happen if updating begins.
Biting the hand that feeds IT
