I'm not sure which driver you are using, but you might try disabling NCQ on 
the drive.  There's a couple of different boot parameters depending on the 
driver or device.  If you know you're are using libata, you can disable it 
globally for all drives with libata.force=noncq.  But you'll probably want to 
dig further to limit it to just the controller and/or drives affected.

You should also post this issue to the linux ide mailing list.  See 
http://vger.kernel.org/vger-lists.html for how to subscribe and the archives 
of the list.  The members of that list should be able to help figure out the 
problem (even if disabling noncq works as a workaround).
