[Bug 328053] Re: No DMA for DVD-burner on ULi 1695 chipset

[Dimitris Kalamaras]

Hi,

I had  similar speed problems (due to missing dma setting) in my Ubuntu
Jaunty installation with my 2 x ATAPI LG DVD Drives on an ASUS A8R32-MVP
Deluxe (ULi M1575 Southbridge). I tried these workarounds:

Added
1) "options pata_ali atapi_dma=1" in /etc/modprobe.d/options (new file for me!)
2) "echo 1 > /sys/module/pata_ali/parameters/atapi_dma" in /etc/rc.local

and finally I added
 "pata_ali atapi_dma=1" to "/etc/initramfs-tools/modules"

All these to be sure! :)

After the reboot (the dmesg messages still appear!) the problem was finally solved.
Now I can watch and write DVDs at full speed.

I added a similar comment in an older but similar bug report, in case it helps somebody:
