Not able to boot any of elrepo kernel on Dell R740

[veryrandom]

Hi,

I tried to install elrepo kernel in Centos 7.4 on my PowerEdge R740 server, but I've failed.
I can't boot any of elrepo kernels neither 3.x nor 4.x, everything I can see after Grub menu is black screen, no message error, just nothing.
Stock kernel boots seamlessly and Fedora Server with kernel 4.19 as well.
First thing I've checked was SecureBoot feature but it's disabled.
I suspect UEF but what difference can be between stock and elrepo kernels that prevents it from booting?
I would appreciate if you could give any hint.
