It tries to load the device driver for block-major-8 (SCSI), it cannot
because the root file system is not mounted yet. Then it tries to open
root on 08:05 (/dev/sda5), not suprisingly that fails because the SCSI
driver is not loaded.

If you really want to use a module for your boot device then you have
to use initrd. It is much easier to build the root device driver into
the kernel and forget initrd, boot modules are fine for distributions
but a pain in the neck otherwise.
