I am afraid there is not really an sgx team that will recognize or support this tree. The lowest risk for quick solution is to get the rootfs to stop doing what it's doing after 10 mins that provokes the problem. Not trying to make out the problem is not on dss / sgx side, but we have no idea how to solve that internally and don't expect any help from sgx folks in ti, so in a case of 'doctor, it hurts when I xyz' the best answer is 'don't xyz'.
