I have compiled and installed a custom version of the 220.127.116.11 kernel. When I boot my laptop, the kernel gives me two messages. They are as follows.
Ext3-fs (sda1): couldn't mount because of unsupported optional features (240).
Ext2-fs (sda1): couldn't mount because of unsupported optional features (240).
I have looked online for this issue, but the closest I can find is this.
Like I said, it will boot, but not before it gives me these messages.
Here are the outputs for the commands requested in the other post.
fdisk -l /dev/sda

This is all the relevant data I can think of to enter. I would like to say thank you in advance to anyone who is willing to help.
