Public bug reported:
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
[ 3.520434] pata_ali 0000:00:16.0: PCI INT A -> GSI 21 (level, low) -> IRQ 21
[ 3.520571] scsi4 : pata_ali
[ 3.520633] scsi5 : pata_ali
[ 3.521957] ata5: PATA max UDMA/133 cmd 0x1f0 ctl 0x3f6 bmdma 0xff00 irq 14
[ 3.521960] ata6: PATA max UDMA/133 cmd 0x170 ctl 0x376 bmdma 0xff08 irq 15
[ 3.684455] ata5.00: ATAPI: PIONEER DVD-RW DVR-110D, 1.17, max UDMA/66
[ 3.700450] ata5.00: configured for UDMA/66
Beyond this I'm not sure what to do??
