I have intel i5 processor, 4GB ram, AMD Radeon R5 Series M330 Graphics, hp laptop. I installed latest ubuntu 16.04 LTS on it. It worked for only 1 day. After that during boot time a error prompts
radeon VCE init error (-22)
and machine suddenly stops. Even It needs several attempts to boot from usb. During USB boot ubuntu logo appears for few seconds and system suddenly stops. Grub is accessible. I also shown this machine to service center they are telling that this is OS problem.I am not able to access my machine.
