I'm having a good experience with it, but I would use it at least with kernel
2.6.28 and up (when it went from ext4dev to ext4). The problem is that ubuntu
and debian live and rescue cds are kernel 2.6.27 and 2.6.26 respectively so
they won't be able to boot into the system. Also if you want boot on the ext4
partition you will need to use grub2 as grub doesn't support ext4. The last
thing is that laptopmode doesn't seem to work as well with ext4 as of now.
