I upgraded from 7.3 to 7.4 over the weekend. Everything went well except that I can't login because the screen is black with a cursor. If reboot boot the 7.3 kernel 3.10.0-514.26.2.el7.x86_64 kernel everything works just fine, so my guess is that there's a kernel issue with the hardware, specifically the Skylake processor. Has anyone else run into this problem and if so can how I resolve the problem other than using the previous kernel? ASUSTeK COMPUTER INC.
