(and same errors apply to current situation) https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1616830/comments/5 Also Ubuntu 16.10 and newer releases do not boot anymore (as reported by a user, I think it is due to kernel). He also reports the same errors with the 4.8 kernel. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1616830/comments/15 It seems that official release kernels still have the same problems and nothing was fixed. There seem to be many problems with Ubuntu on Carrizo, black screens, random freezes. I myself experienced, keyboard problems (keyboard sometimes do not register keystrokes), touchpad works strangely, random freeze with caps-lock blinking, low disk performance (max 1.3mbytes/sec) and much more. I do not understand how hardware support can be getting worse and worse, but that seems to be the case.
