the wrong way to create image from sanpshot

If you create a EC2 image from the the sanshot which is a wrong way, you will end up with below error message:

EXT3-fs: sda1: couldn't mount because of unsupported optional features (240).
EXT2-fs: sda1: couldn't mount because of unsupported optional features (244).
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(8,1)
 
 
The wrong way is:
1. Create sanpshot from the running instance volume
2. Click the created snapshot and create image from the snapshot
3. Launch instance with the created image
 
The correct way is:
1. Create image from the running instance
2. Launch instance with the created image
 
That's it!
