Hey all A few months ago, Michal Suchanek submitted the attached patch fixing the gating timeout issue. Until recently, about v4.0.0 I hadn't noticed any issues and ran all boards from SD card. Recently I upgraded to Hans's 4.2 tree where he added mmc: sunxi: Don't start commands while the card is busy which started to trigger the timeout very aggressively causing a pretty much unusable system. While reverting the commands patch also removed the problem for some reason, that is of course not the real fix. Applying Michal's patch on top of the commands patch appears to fix the issue on atleast the A20 Lime2. Attached I have Michal's original patch, rebased to 4.2.0-rc5, with Hans's patch applied before hand. Changed since v1 * Whitespace cleanup as suggested by Maxime Ripard, no functional changes from that patch Olliver
