What Is Kernel Panic Error
Kernel panic issue or error is one of several Linux boot issues. In this issue, the kernel can’t load properly and therefore the system fails to boot. During the boot process, the kernel initramfs loads in RAM, not load directly. Then it points to the kernel and then the operating system boots.
When a Linux system boot process starts after the Master Boot Record (MBR) step, GRUB is loaded. The kernel needs to be loaded into RAM to start the OS, but the kernel is situated on the hard disk (/boot/vmlinuz), and the hard disk is not yet mounted on /. Without mounting, no files can be accessed, even the kernel. To overcome this, first initramfs/initrd loads in RAM directly and mounts the /boot partition in read-only mode. Next, it mounts the hard disk on the / partition, and the process continues.
Why do kernel panics occur?
- If the initramfs file gets corrupted.
- If initramfs is not created properly for the specified kernel.
- If the installed kernel is not supported or not installed correctly.
- If recent patches have some flaws.
- If a module has been installed from online or another source, but the initrd image is not created with the latest installed module.
