Hi, I have installed a Pioneer DVD burner (DVR-215) in my system. The mother board is an Asus only 6 months old. Basically the drive is detected by the system but sata_via complains and generates some errors in the log and then the driver will not work after this. I was running kernel 2.6.25.4, and upgraded to 2.6.26.3 but this did not fix the problem. The following is the output from dmesg .... dmesg ...
