More comments on the subject:
One way to test the effect of disabling dma is to "try setting
ide=nodma in your grub.conf or on the bootup command line" as suggested in
https://www.redhat.com/archives/redhat-list/2003-June/msg01639.html . And
of course the problem might be that your disk is dying, in which case the
solution is to back up what you want to keep and then replace the disk.
