Any news about this? At the end I had the impression that this is

Hi Tejun,
Sorry to say, but after applying your patch it still doesn't work.
If I insert the DVD and wait before running xine, then I can watch
it. But if I keep the tray open and run xine, then xine closes
the tray. It gets stuck for some time, and then I get

If these commands result in packets their size is not zero. Not all

A thing that crossed my mind was a timing issue. Perhaps the dmaing of
60 bytes is that
fast that the interrupt that causes it is not yet handled correctly. But
this is just a very wild guess.
I don't think that can happen. Controllers are required to queue
interrupt till FIFO is
