A stop/reassemble circle will tell us if this is > the issue. If the issue was in the script it would happen with all the kernel version no? Si far 3.14, 3.18, 4.1 works correctly (when upgrading). Only 4.4 fails. 4.4 in fact seems to fails to boot the first time I boot it. As I have no console normally, I have to shut down via power button and then it resync. I can understand this behavior but not 1) that the resync fails each time and 2) that it fails to boot the first time I change for a 4.4 kernel. -- eric
