I had the same problem "Mkinitrd failed" and solved it with the following actions :
- remove my Initio Scsi adapter
- completely reinstall the system (mandrake community 10)
- plug theScsi card in place and add line in 2 files :
In file /etc/modprobe.conf add :
install scsi_hostadapter /sbin/modprobe initio; /sbin/modprobe imm; /sbin/modprobe ppa; /bin/true
In file /etc/modules.conf add :
probeall scsi_hostadapter initio imm ppa
Now disks and scanner connected to this adapter are working fine.
May be this can help you.
