Summary; Copied / from sda3 to sdb3 Updated the fstab in the new disk (/dev/sdb3 / btrfs noatime,compress=lzo 0 0) Updated the kernel line's root=/dev/sda3 to /dev/sdb3 in grub.conf, but left the root (hd0,0) as it is. So, kernel is loaded from sda but init should run from sdb. When booting the kernel successfully mounts /dev/sdb3 as root fs Then the system halts at one of the freeing memory messages, but I assume the problem is that init isn't executed from /dev/sdb3
Since root is mounted, i know i have all the drivers I need in the kernel. Any ideas why booting stops?
