grub2-mkconfigbreaks the expected boot order of kernels -- the latest kernel is no longer in position 0.
grub2-mkconfigcommand is not appending proper kernel menu entries in
/boot/grub2/grub.cfgfile. It is causing system to boot with older kernel.
Install latest (or multiple) kernel on RHEL7 and run
grub2-mkconfig -o /boot/grub2/grub.cfgcommand. It is not sorting entries from latest kernel to older one. To Verify:
grub2-mkconfig | grep ^menuentry
- Red Hat Enterprise Linux 7
- grub2 less than or equal to version
