I have an A8 3820 AMD cpu (HD 6550 graphics) I have the same problem. First I want to say that I have been booting a usb hdd since 16.04 alpha. when I booted kernal 4.4.0-10 no problem, but I then booted to 4.4.0-12 that's when the problem started. Then I waited for the release of 16.04, there was no change. I just booted the live dvd using nomodset option and the screen showed an error "no ums support on radeon module." I don't have any other driver installed except what's in the kernel.
