I had the same issue on my thinkpad, getting rid of the whole IDE stuff solved the problem (because the other drivers does no longer grab the drive). This ThinkWiki entry should apply to your laptop just as well, just replace /dev/hda with /dev/hdc. http://www.thinkwiki.org/wiki/Problems_with_SATA_and_Linux#No_DMA_on_system_hard_disk > also this laptop has nothing on ide0 - both the harddrive and dvdrom are > on ide1. > is this confusing things? Probably ide0 is pure SATA, while ide1 has the PATA adapters (just a guess).
