My first guess is you did not enable DMA on your drive. You can check
this with hdparm. For example, if your drive is /dev/hda then type
'hdparm /dev/hda' and see if you get a line saying 'using_dma    =  1
(on)'. If you see it off, turn it on with 'hdparm -d1 /dev/hda' and
see if the problem goes away.

If the DMA setting does fix your problem you need to turn it on during
boot up. The simples way might be to install the hwtools package
(apt-get install hwtools) and then edit the file
/etc/init.d/hwtools. You will see where to uncomment/add the hdparm
commands easily.

No doubt about that.
