I got a new Dell R530 server recently and have installed Centos 7.5 (1804) on it (tried 17.04 as well!). I installed new kernel from elrepo on the system. The issue I am encountering is that if I boot from new kernel I would not get console (I can still SSH but no console on the machine), but if I boot from the default kernel (the kernel that centos comes with), things work! I have updated kernel on other R530 machines we got in the past without any issues! Any idea what might cause this and if there is a fix for it?
