Thanks! I'm using your yocto image and this script, but I still am not
encountering the problem. I'm building next-20140114 using the
randconfig you sent in the original report. It looks like you're built
against a slightly different kernel version? Is there some way you can
push the tree you're building to git somewhere for me to fetch?
