Kernel Panic
Also known as: panic, oops
A fatal kernel error from which Linux cannot safely recover, so it halts the system and prints diagnostic information.
What Is a Kernel Panic in Linux?
A panic happens when the kernel detects an internal problem it cannot handle, such as failing to mount the root filesystem at boot or hitting corrupted memory. An "oops" is a less severe error the kernel may survive.
Common causes are bad hardware, a broken initramfs, faulty drivers, or wrong root parameters. The last lines usually name the culprit; booting an older kernel from the GRUB menu is the quickest workaround.
