This produces a failure to boot as the wrong partition is mounted as root (/dev/mmcblk0p2 is now on the wrong mmc). The bisect tried all the mmc tree patches which were all good. I double-checked by cloning the mmc tree and building both mmc-v4.6 and v4.5-rc6, and both tested good. I interpret that to mean some change in mmc + some new behavior elsewhere for v4.6 is causing this. Any ideas? Regards, Peter Hurley
