Re: libata access to pata drives breaks dma/32bit mode?
Are you saying that libata is supposed to always enable 32bit dma transfers?

It seems that hdparm does not work on the devices created by the libata driver, so how are you supposed to enable 32bit and dma transfers? Several users have been having trouble because they can not find a way to enable them and thus, have poor performance under feisty.
