Meaning the same install was working before with another motherboard?

Yes, most probably the kernel does not know how to handle ide dma on
that chipset (just a guess, of course, it depends on how new is the
mobo). You can check how the parameters for the disk are configured by
saying:

  /sbin/hdparm /dev/hda

Is it working correctly with the RedHat kernel?
