Brasero burns very slow in Jaunty

[David]

Binary package hint: brasero

Burning CD's and DVD's in Brasero is very slow (over 1hr). The same procedure using Brasero in 8.10 was about 10 minutes. Also burning img from command line (growisofs) is also fine.

I have found that the problem is related to DMA. I read some info in other places about this. His is a work around (but causes another problem I'll explain in a moment.

add "options pata_ali atapi_dma=1" to /etc/modprobe.d/options (new file)
add "echo 1 > /sys/module/pata_ali/parameters/atapi_dma" to /etc/rc.local
add "pata_ali atapi_dma=1" to "/etc/initramfs-tools/modules"

The problem is with DMA enabled, any time I do any kind of disk intensive operation (ie. copy a large amount of files from one partition to another.) I cannot do anything else until the operation is done as the system becomes unresponsive. But it does seem to resolve the issue although I have only burned one DVD since finding this issue. As a work around I can run:

echo 1 > /sys/module/pata_ali/parameters/atapi_dma and then echo 0 after. Perhaps that would be something to consider from within Brasero? Or perhaps there is a way to only enable DMA on the DVD and not the HD? I'm out of my league on this so just random thoughts.

As far as trying in Karmic, unfortunately, I'm not in a position to do that until it is production ready as my machine is in constant production use.

not a brasero issue then, this need to be reassigned.

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue that you reported is one that should be reproducible with the live environment of the Desktop CD of the development release - Natty Narwhal. It would help us greatly if you could test with it so we can work on getting it fixed in the next release of Ubuntu. You can find out more about the development release at http://www.ubuntu.com/testing/. Thanks again and we appreciate your help.
