What chipsets are you guys using?
I tried 2.6.20-rc6, and forced my cdrom to be used by the ide piix
driver instead of the sata one, so the device shows up as hda instead of
a scsi one. And, if I use the ide piix driver for the cdrom then it
works fine. I see IO going through the block layer sg io code which was
modified in 2.6.20 to support larger IOs.
Strangely, if I use the sata driver, then nero uses the sg driver
(drivers/scsi/sg.c) instead of the block layer sg io code. But the sata
code spits out:

nero still works in this case, but is is sluggish. It takes a couple
minutes to start up and on almost every operation like "Choose Recorder"
spits out more error messages like above.
This may be not be related. I am going to keep digging around.
