Could be, but: git checkout -b blah 69fd70c7ff31d3f00833c472c3994a02bb0ab287 # can not mount the rootfs via nfs git revert 69fd70c7ff31d3f00833c472c3994a02bb0ab287 # boots up via nfs rootfs. When my HEAD is 69fd70c7ff31d3 and I revert only the topmost commit (69fd70c7ff31d3), the board boots. It could be that the ethernet not working is just a side effect of something else going wrong, but this is the indication I have. Nothing special in the logs, I can share the two bootlogs: 1. HEAD at 69fd70c7ff31d3 2. HEAD at 69fd70c7ff31d3 and reverting 69fd70c7ff31d3 But only tomorrow. - Péter Texas Instruments Finland Oy, Porkkalankatu 22, 00180 Helsinki.
