    VFS: Unable to mount root fs on unknown-block(8,3)
    This error means kernel is trying to access the third partition of first hard drive and mount it as root filesystem.
    Since this is not happening ...

    0. make sure third partition of first drive contains your root filesystem;

    1. make sure support for root filesystem is included in kernel (not as module).
    These are the filesystems supported by your kernel: ext3 ext2 cramfs vfat msdos iso9660 romfs
    However, earlier there is an error
    ETX3-fs (sda3): error: couldn't mount because of unsupported optional features (240)
    which implies you may be using EXT4.
