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.

Pete -------------------------------------------------------------------- Pete, I have had various assortment of problems with 7.4 to the point that I quit upgrading the rest of our PC's with 7.4 until the problems are identified and fixed. The only work around that I could come up with is to use the last 7.3 os which at least made each unit usable. As you know, most of the time these upgrades have been seamless because the Centos team has done a wonderful job. However, the upgrade to 7.4 has some problems, and I decided to stop the upgrade of our remaining units until 7.4 works as well as 7.3.
