How to solve kernel panic error in Linux

 

Troubleshoot | RHEL-7 Kernel panic error

Before I start to write about this, let’s understand that kernel panic can be a cause of many different reasons related to Linux Kernel.when kernel tries to load itself to memory, if it finds any difficulties, it provides with some kind of error in the form of Kernel panic.

I have even faced other issues related to kernel panic, but those happened while I was trying to migrate a Linux VM to AWS cloud & that happened because the source Linux had some custom module which was not supported for AWS. So the migrated instance at AWS gave kernel panic.

So, it’s really difficult to post all the use cases in one blog article. So attempting to start with a simple one first.

Below is an example that I came across in recent days and hence wrote a few lines.

This happens mostly because of the initramfs.img file missing or corrupted

1.Boot the system in rescue mode

2.Login using root account

3.Navigate to /boot

4. See if initramfs.img file is available (If it is available, it must be corrupted

    Arh, this mostly happens because of dodgy hardware. So this is a quite a bit more complex than your explanation
