[ol8_MODRHCK] kernel-debug-core-4.18.0-553.81.1.0.1.el8_10.x86_64

The kernel package contains the Linux kernel (vmlinuz), the core of any
Linux operating system.  The kernel handles the basic functions
of the operating system:  memory allocation, process allocation, device
input and output, etc.

This variant of the kernel has numerous debugging options enabled.
It should only be installed when trying to gather additional information
on kernel bugs, as some of these options impact performance noticably.
