Doesn't look like the DVD-ROM is connected via PATA or SATA, looks like it's actually connected via a USB connection internally? That seems a bit bizarre.. Can you do a lsusb to verify if that's the case? If it is, then the kernel doesn't have any control over the DMA state of the drive, as that's purely under control of the USB-to-ATA bridge chip they're presumably using. ^ permalink raw reply [flat|nested] 2+ messages in thread
