Based on some very unscientific testing, I found that somewhere between 1 and 1.5A minimum seems to be the success threshold. I inadvertently used a 1A adapter when I booted remix for the first time, and spent way too much time scratching my head wondering why it wouldn't boot. It got me to doing some very unscientific testing, was able to boot all 3 OSs (debian, android, remix) with a 1.5A Pi adapter, and, of course, it does fine with a 2A supply. The 1A supply is hit or miss, depending on whats connected, the OS I'm booting (sort of surprising there..), etc.
I still do believe there is an voltage output stability factor involved here also, but its so easily avoided just by using a solid stable 2A adapter I'm not of the belief it warrants a lot of testing to shed light on a problem that is easily avoided.
