I believe your complaint was for 2.4, since it doesn't support SG_IO for atapi devices. For 2.6 you are just wasting cycles using ide-scsi on ATAPI burners. > >use dma for all transfers.

I have lots of discussions on linux-kernel, and not all of them (very few, in fact) end up in flames. You seem to end up in flames with basically everyone. At least on linux-kernel, I believe my track record is far better than yours. Your mails are often infuriating. Since you do not listen to anything I say anyways and keep reiterating the same comments again and again like a duracell bunny, it's hard to have a technical discussion with you. End of discussion from me. Before you claim I'm going away because I have no arguments (that's rich, coming from you), I'm closing this thread from my end since you bring nothing to the table except flame bait and repeated empty arguments. -- Jens Axboe
