Comment 34 for bug 569680

@Giuseppe: The command `lspci` should give you an idea. For instance, here's my lspci output:

See the line in there about my Silicon image SATA controller? Even if you can't pick out which line is your hard drive controller (some onboard ones may not be as obvious) it might help to post your lspci output so others can see what you have. I don't know anything about kernel development, so I was justing guessing about the controller driver being a possible issue; however, I'm sure any information we can provide for those who know what they're doing will be of assistance.
