This surprises me.  Since you said it works on Windows, I think the
problem is still in the DMA settings.  I would do a google search for
other people using Linux on this laptop.  See if they have had this
issue and what solutions they may have come up with.

You could also look at hdparm's man page and see if there are some
more tweaks to use.  See if it's using 32bit I/O etc.  I'm sure that's
where the problem is, but I'm not too sure about any further
specifics.  Have you tried the on-line Ubuntu forums?  I've gotten
help there several times.

Sorry my reply took so long.  I've been away from the computer.
