Bug Description
DMA is disabled on Intrepid
Managed to turn it on using the following...
edit /etc/initramfs-
pata_ali atapi_dma=1
Then, update the initramfs
sudo update-initramfs -u
Then reseting machine
But now the UDMA is set wrong...
sudo dmesg | grep ata

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

i'm having the same nasty issue, which must be chipset related. www.asrock. com/mb/ overview. asp?Model= K8%20Combo- Z&s=939)
(my mb is a k8 combo-z, using uli(ali) m1689 chip :: http://
since intrepid beta (and now using the final release) i tried pretty much everything i read here and there, but no luck so far..btw this regression comes from the newest linux kernels - not only ubuntu intrepid users are having this problem.
i hope a workaround will be found or that a new kernel will fix this embarassing issue!
cheers =)
