[Bug 31709] Re: Brasero, GNOME's burn:/// and K3b slow dvd burn speed

[gonen]

Had a similar problem.
DVD burning was extremely slow (below 1x speed), took forever to write DVDs.

sniffing around the web and looking at my system I found the following
in dmesg:

[   31.521623] ata1.00: ATA-7: FUJITSU MHV2060AT PL, 000000A0, max UDMA/100
[   31.521627] ata1.00: 117210240 sectors, multi 16: LBA
[   31.537571] ata1.00: configured for UDMA/100
[   31.857052] ata2.00: ATAPI: TSSTcorpCD/DVDW TS-L632B, LG34, max UDMA/33
[   31.857068] ata2.00: simplex DMA is claimed by other device, disabling DMA
[   32.028830] ata2.00: configured for PIO4

I found this:

I did the suggested solution:
 - in /etc/initramfs-tools/modules , added
pata_atiixp
blacklist ata_generic

 - then:
sudo update-initramfs -u

results are amazing...
from the ridiculous speed of 1x (and below) I got a burning speeds of up to 6x

dmesg no shows

[   28.016707] ata1.00: ATA-7: FUJITSU MHV2060AT PL, 000000A0, max UDMA/100
[   28.016710] ata1.00: 117210240 sectors, multi 16: LBA
[   28.032662] ata1.00: configured for UDMA/100
[   28.352140] ata2.00: ATAPI: TSSTcorpCD/DVDW TS-L632B, LG34, max UDMA/33
[   28.523889] ata2.00: configured for UDMA/33

hope this will be helpful for others
