I encountered this issue with Ubuntu 10.04 and ASRock K8SLI-eSATA2 motherboard.
=> http://www.asrock.com/mb/overview.asp?Model=K8SLI-eSATA2
The Kernel I'm using is => 2.6.32-27-generic-pae #49-Ubuntu SMP
I tried post #85's instructions, but it causes more problems than it
solves...
The DVD burner is connected to PATA connector (Primary - Master). HDD is
SATA

[ 0.368488] ata1.00: configured for UDMA/66
An issue appears the first time...

* The system obviously up slower.
* Burning DVDs uses 80% CPU load instead of 95%.
* Burning speed is slower. (From 2.20x down to 1.90x; according to K3b)
...And the whole system feels notably sluggish. Maybe I'll switch to a
USB DVD burner as a work-around.
