Hey all,

I heard that with the 2.6.15 kernel SATA pass through support has been added. Does anyone know if this is what is necessary to make DVDs play well on an Inspiron 6000? I thought I read that the problem with enabling DMA on the DVD drive was because of the SATA DVD drive.

I just compiled a 2.6.15 kernel, but it did not seem to fix the DVD problem. DVD playback still stutters a great deal. Is there some other option I need to add in the kernel config file? Or do I need to pass a kernel parameter?

Any suggestions are welcome.

Thanks,
Chris

Hi,

According to comment #35 in Bug 163418 at redhat.com,

>Note that vanilla kernel 2.6.15-rc5 still defaults to libata ATAPI disabled, and
>needs the libata.atapi_enabled=1 argument (for built-in libata) or "options
>libata atapi_enabled=1" modprobe.conf line (for modularized libata).

If you try passing that kernel option, please let us know if it works!

I checked that link and it looks like adding this line to my lilo.conf should fix it:

append = "hda=noprobe libata.atapi_enabled=1"

but that doesn't change anything. Is this the way you pass kernel parameters using lilo?

I'm sorry for bumping this up, but I'd really like to know if anyone has managed to get DMA enabled on an Inspiron laptop.

Thanks

I don't remember lilo very well since I haven't used it in a while. But make sure you rerun lilo to write the new settings to the MBR if you've made any changes. Also, if I remember right, you could just add your kernel arguments after the prompt, for example:
LILO: linux libata.atapi_enabled=1

You might also have better luck asking in Slack-specific forums since this issue is not unique to the Inspiron 6000. If anyone else here has better information, please speak up!
