Hi Fathi,
Samsung Origen boot failed, but this failure is different with the one we had before.
New Bug: https://bugs.launchpad.net/linaro-ubuntu/+bug/1109964
Old Bug: https://bugs.launchpad.net/linaro-ubuntu/+bug/1087505
For the issue described in old bug, kernel panic only happened if we change the network settings manually and restart the system; but the new issue is simply boot failed, power on, then boot failed.
Thanks.
Best Regards Botao Sun
