Date: Sun, 15 Jul 2007 21:26:14 +0200 From: Zoltan Boszormenyi <zboszor@...aweb.hu> To: linux-kernel <linux-kernel@...r.kernel.org> Cc: Jeff Garzik <jgarzik@...ox.com>, Alan Cox <alan@...rguk.ukuu.org.uk> Subject: DVD-playing, ide-cd vs scsi-cd drivers Hi, I have an FC6 machine with a Pioneer DVD-RW and I occasionally watch DVDs on it. (Xine+libdvdcss from Livna works just fine.) I compiled 2.6.22-rc7-git5 before with ide-cd but now I changed the driver to pata_amd to see it works before I upgrade to FC7. Now DVD-playing doesn't work, I got this in the log when I tried to play a DVD in Xine.

Sense: Logical unit communication CRC error (Ultra-DMA/32) end_request: I/O error, dev sr0, sector 9127460 I changed the driver back to old IDE and DVD-playing works again so it's not a hardware error. Is there something I forgot to compile in or is it a handicap in the SCSI CD drivers?
