hdd: dma_intr: error=0x84 { DriveStatusError BadCRC }

Кто-нибудь сталкивался с чем-то подобным? Как полечить?

На втором IDE разъеме висят диск и DVD-RW (чипсет - Gigabyte M55plus-S3G). Режик выставлен мастером, диск - слейвом (пробовал оба и на cable-select - все то ж).

Вот такая ругань в логах:
