Comment # 21 on bug 1213222 from Stefan Hundhammer

install.inf from the y2logs tarball contains this reference to pata_atiixp:

> InitrdModules: scsi_dh scsi_dh_alua scsi_dh_emc scsi_dh_rdac pata_atiixp ata_generic cdrom sr_mod usb-common usbcore usbhid st sg thermal iscsi_boot_sysfs

Probably dracut uses 'lsmod' to check what kernel modules are currently loaded
(i.e. what hardware the kernel detected), and it detected a chipset that needs
the 'pata_atiixp' kernel module, which in turn might require the 'atiixp'
module (AMD / ATI hardware?).

I can't verify that because I don't have any hardware that needs those kernel
modules. But you could check with

  hwinfo  | grep module | grep atiixp

If that doesn't give you any results, please attach the output of `sudo
hwinfo`.
