Comment 2 for bug 8155

Ahem, I feel kinda stupid now because suddenly it also boots when I pass
root=/dev/sda5 (which is the S-ATA partition) to the kernel. Only the root
option of Grub still needs to point to the P-ATA disk, which doesn't look like
it's an Ubuntu problem. Could the problem be, that Ubuntu is installed on a
logical partition? I don't think I ever had problem with this though.

In any case, at least the CDROM detection problem at installation still remains
and is very critical (to me), please tell me if there is any additional useful
information I could gather after booting from the CDROM.
