Comment 18 for bug 175022

Thanx,

+ adding options pata_ali atapi_dma=1 to /etc/modules
or
+ adding pata_ali.atapi_dma=1 to boot options (unrecognized command)
did not work,
still error in dsmeg and choppy video

also sudo echo 1 > /sys/module/pata_ali/parameters/atapi_dma did not work (permission denied).

output for hdparm -i /dev/sr0 indicates udma2 mode
(disks are in udma5mode)
