I don't think so as the system has been very stable with DMA enabled for all devices, the only difference is that RH8 worked with hdd=ide-scsi in my grub conf. On RH9 if I put the hdd=ide-scsi back in, I will lock up with five minutes. Besides without DMA enabled on the burner and I going to be able to write disks faster than say 4x?
