[-- Attachment #1.1: Type: text/plain, Size: 643 bytes --]

I cloned the kernel from "git clone git://
git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git".
I selected the branch 5.7.y for building the kernel, I used the command
"make menuconfig" to select specific  modules  and to avoid other options
that come up while making the .config file.

I was able to successfully install the kernel but when I started the kernel
version 5.8.3+ , the system freezes with the message "see systemctl status
kdump.service".
When I looked in the logs I found this message "Failed to start Crash
recovery kernel arming"
My operating system is Centos 7.8.2003 kernel 3.10.
Any help will be appreciated.

Hey,

This superuser post presents a solution, that might be helpful:
(https://superuser.com/questions/1463319/how-to-fix-failed-to-start-crash-recovery-kernel-arming-when-can-not-enter-the)
from Juli.2019

And as stated in this forum post, you can maybe find a bit more information
on your problem by disabling the `rhgb quiet` option.

I tried changing the crashkernel value but nothing happened.
I got the information about the problem and I searched it and found that it
might be due to graphic drivers.
But the problem is that I don't know which config settings are used for
that.

Try to duplicate the CentOS  kernel's config instead of using/creating your
own, you probably missed one or more needed config item.

Or better, use rpm/rpm source from elrepo (google for the url). It takes
stable/mainline kernel and make it (as much as possible) work with CentOS

Mind you that CentOS 7 is based on 3.10.x kernel and you're trying to run
5.x kernel, something that might not work due to incompatibility of API/ABI

Hope it helps
