I've a similar machine

and have had this problem in the past.  Make sure you are using the
latest 2.2.19 ide patch (ide.2.2.19.05042001).  My problem was marginal
ATA/66 IDE cables that came with my motherboard (Abit KA7).  Other than
upgrading cables I also use kernel param 'ide0=ata66' at boot and these
.config entries:

CONFIG_M686=y
CONFIG_MTRR=y
CONFIG_IDEDMA_AUTO=y
CONFIG_BLK_DEV_VIA82CXXX=y

Also it could be EIDE cables too long or not fully inserted or damaged
(pinched), or an actual disk failing, or excessive heat in the box if
the disk is very hot to the touch.
