Interestingly, the same u-boot (2013.4 + Patrick's patches) works with 11-CURRENT but not 10-STABLE -- that's booting from eMMC, there are no issues booting from SD; also once booted from SD, there is no issues mounting the eMMC and accessing it (well ... aside from lock reversal warnings and the occasional sdhc timeout). Is there a way to debug this? Thanks!
