I have two desktop units with : Intel(R) Core(TM) i7-7700 CPU @ 3.60GHz that do not allow the login screen to appear after the update of :
kernel-3.10.0-693.5.2.el7.x86_64 and kernel-3.10.0-693.2.2.el7.x86_64
Both of these units worked properly with kernel.x86_64 3.10.0-514.26.2.el7
I am not sufficiently familiar with grub to know if the problem is related to grub or related to the kernel. I have been able to boot the machines by the use of kernel.x86_64 3.10.0-514.26.2.el7.
When using kernel-3.10.0-693 the login screen is blank and the login prompt is missing, however each machine is accessible via the terminal interface, or remotely with ssh.
Does anyone have any ideas ?
