Tested-by: Xiaolong Ye Wonderful, thanks for letting us know. It's been in linux-next since Tuesday of this week. Perhaps your testing could see if patches further along in the specific branch you hit solve the problem you are having before you need to report the issue? Yes, good idea! It could be made more smart like that. Thanks, Fengguang
