This is a big problem with amdgpu on the Carrizo card. The screen just goes black, and I am unable to get it to do otherwise, even after rebooting. Using nomodeset as a kernel parameter during grub boot-up allows me to boot it up in low-graphics mode.
I do not have this issue in Ubuntu 14.04, since Ubuntu 14.04 still allows users to install fglrx/Catalyst, which works perfectly with Carrizo. But support for that package has been dropped in later installments of Ubuntu.
