Is DMA enabled for the disks? If ide-generic is running the controler instead of a native driver you don't get DMA which means all IO is slow and uses a lot of cpu. Check /proc/ide/ or if sata it should be enabled (unless you run sata in old ide compatible mode). Len Sorensen -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
