Hey folks,

I just tried to install User Mode Linux in my laptop for a research project in order to test a kernel module but couldn't succeed. The error that I keep on getting is :-

EXT3-fs: ubda: couldn't mount because of unsupported optional features (240).
EXT2-fs: ubda: couldn't mount because of unsupported optional features (240).
List of all partitions:
6200    1048577 ubda driver: uml-blkdev
No filesystem could mount root, tried:  reiserfs ext3 ext2
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(98,0)

This is a part of the entire log. Any help would be appreciated.

Regards,
Sarthak Dash
