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: https://bugs.launchpad.net/ubuntu/+bug/292142 -- No DMA for DVD-burner on ULi 1695 chipset https://bugs.launchpad.net/bugs/328053 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
