Guessing you are using and SATA/PATA controller ?

Combined mode got removed in 2.6.22 and depending on your config things will break.

As example CONFIG_IDE=y  BLK_DEV_PIIX=y , ATA=y , ATA_PIIX=Y worked in <2.6.22 but won't on .22.

If you want to use libata try to boot with ideX=noprobe ideY=noprobe
