ubuntu dma issues with Tosh A55

[riker1]

Hello,
I have a Toshiba A55 1.6 celeron laptop, Ubuntu installed fine except when
I try using xine its choppy...Tried turning on dma using all the normal ways using
dev/hdc...dev/cdrom...dev/dvd d1 yadda yadda...no luck...comes back
dma cant set,something about incorrect controller usage? Im still a newbie
so ecuse my ignorance, but cant help thinking it has something to do with
disks being listed as scsi ...any help is appreciated, merely want to kill the chop
on dvd playback...final note...my old tecra 8100 never had this issue...

I had a similar issue on an old Dell. You need to recompile you kernel and add in the support for your controller. I think I basically just enabled all the various IDE controllers listed because I wasnt sure exactly which one was correct.

I followed the instructions on the Ubuntu support wiki on recompiling the kernel.

You will also need to set Grub to boot the newly compiled kernel by default.

Sounds daunting, but you can do it.
