I would like to compile and use a realtime kernel on CentOS 7. I found a guide on the web: http://jensd.be/589/linux/complile-and-use-a-realtime-kernel-on-centos-7-or-rhel-7

When I try to use it I can see the new kernel is created, but I get an error on boot:

failed to mount /sysroot
  • What kernel, which patch, and which .config? – Panther Jan 1 at 17:11
  • sorry - kernel 3.10.0-514.el7.x86_64 , patch is patch-3.10.105-rt120. .config is according to the one that came with my kernel – Avner Gidron Jan 2 at 9:25
