Bug Description
When trying to enable (so i can burn DVDs faster than x2) DMA on my NEC-DVD
burner I get the following error:
/dev/hda:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)
I'm using the "-686-smp" kernel packages
I'm pretty sure this is a issue with ubuntu, and not the drive. Since I also
have a gentoo install on my system, where I'm allowed to enable/disable DMA on
the drive.
