I wanted to check if the problem was pre existing or a result of a potentially bad merge on my part. It sounds like reboot wasn't a big concern for the raspberry Pi engineers. Wow, weird.

Thanks for the suggestion. I'll try it out when/if they ever have the zero available in Canada for a comparable price. Do you use the pi or pi2 kernel for zero?
