Ok, marking this as Rejected as you added those hdparm lines yourself.

If the documentation that told you to do that was from an Ubuntu source, please ask the author to remove it; on Ubuntu dma is enabled automatically if it's possible -- forcing it to be enabled can cause problems.

The reason you were having problems is due to hdparm being unable to enable dma itself, which isn't needed because it was already enabled anyway.
