aix78xxx, scsi drives only. While booting the initrd image no scsi disks are
detected at all and thus the mounting of the root partition fails.
The dmesg messages from the working (-2) kernel:

the -3 kernel reports 'no scsi devices' or something simillar if i remember
correctly.

I'm sorry but I don't have the -3 kernel. From the -2 version:
-rw-r--r-- 1 root root 251651 Jan 1

Also, please have a look at other comments since someone confirmed a problem
with aic7xxx.
