Thanks for detailed information to help me boot ubuntu on acer tab a500, now I am able to boot it with ubuntu and reproduced the issue with v11 patch-set.
I will start to investigate the root cause, from now on, my update patch-set will be tested on both samsung chromebook pro and acer tab a500
Thanks for your help
Thanks, Jiada
