Any SDHCI failures in Linus' tree (but not linux-next) that occur only in multi_v7_defconfig are likely solved by: http://lists.infradead.org/pipermail/linux-arm-kernel/2014-June/264012.html [PATCH] ARM: multi_v7_defconfig: re-enable SDHCI drivers > Whether these are caused by the patch set or not is anyone's guess, > because we (a) don't know what's causing these failures, and (b) > my patch series was never tested on anything but iMX6. I thought that I'd tested at least some of it on Tegra.
