Try passing kernel params (eg- idebus=33 ide0=ata66 ide1=ata6) rather
than relying on hdparm to set up disks.

I'm on 2.2.19pre8 + ide.2.2.18.1221 but same board and cables, zero
errors.  Also run a check with nothing but graphics, kbd, disks.  KA7
seems to be particularly edgy with some addon cards (ES1370 & Promise
controller in my case) and <300W power (compared to P3B-F).
