# linux – How can I install Kernel 5.17 on CentOS 7?

On a CentOS 7.9 installation I have some troubles running newer CPUs, e.g Ryzen 5 5600G (with included graphics).

I concluded that it is the Kernel because it boots with certain versions, with kernel 5.4.219-1.el7.elrepo.x86_64 for example boots but I see this during boot:

kobject: can not set name properly!
mce: Unable to init MCE device (rc: -22)


After that it boots OK, only problem I noticed is that text is very large on console screen, so it must be missing some drivers/packages.

I read that kernel 5.17 has some updates for AMD Ryzen CPUs and I am trying to install this one, but I don’t know how.

I installed 5.4.219-1.el7.elrepo.x86_64 and 6.0.3-1.el7.elrepo.x86_64 (not booting) from el-repo repositories, but I cannot find 5.17 there.

• How / from where can I install 5.17 kernel or how to know which one is good for this CPU ?
• Is it uncommon to try to install 5.17 kernel on CentOS 7 and I should move to CentOS 8/9 ?
• Are the above errors not serious and I should stick to 5.4.219-1.el7.elrepo.x86_64 (only kernel that boots) ?
