DMA CD/DVD Problems in Jaunty

[John Talbot]

DMA is disabled on Jaunty

Managed to turn it on using the following...

Edit /boot/grub/menu.lst
Then add
pata_ali.atapi_dma=1

To the end of the default menu item, Ie...
kernel /boot/vmlinuz-2.6.28-11-generic root=UUID=78f1fb4c-838e-4271-9cf4-595ad7d3c7a1 ro quiet splash pata_ali.atapi_dma=1

Then reseting machine

But now the UDMA is set wrong...

sudo dmesg | grep ata

Beyond this I'm not sure what to do??

Hi Baron,

This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 348241

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.
