Clean installed with Ubuntu 16.04.02 TLS Desktop 64bit
We used some desktop computer to test the android mobile phone. Link to PC
through USB Type-C and Micro USB.
We set an APK file to let mobile auto mount/dismount around 1 time/minutes.
Kernel will intermittent crash, Even test from 16.04.01 LTS same as well.
Seek your advise if any kernel upgrade or idea can resolve this issue.How to
create the trace log for deep analysis if need?
I have attach the log file for your reference, Thanks very much!!
