I was troubled by the same problem. My laptop machine is HP Stream 11 d012tu. It's also using eMMC. (I think it is almost same to HP Stream 13.) I updated kernel version from 3.13.0-48-generic to 3.19.3-031903-generic following the advice of jsalisbury, but didn't update Ubuntu version (kept using 14.04), and then this error disappeared. This thread was very helpful for me, thanks.
