Problems with DVDs (dual layer?)

[dbr]

Hi,

As soon as I put a DVD video in my drive, kern.log starts filling up with:

Aug 7 20:41:35 localhost kernel: hdd: packet command error: status=0x51 { DriveReady SeekComplete Error }
Aug 7 20:41:35 localhost kernel: hdd: packet command error: error=0x54
Aug 7 20:41:35 localhost kernel: hdd: packet command error: status=0x51 { DriveReady SeekComplete Error }
Aug 7 20:41:35 localhost kernel: hdd: packet command error: error=0x54
Aug 7 20:41:36 localhost kernel: hdd: packet command error: status=0x51 { DriveReady SeekComplete Error }
Aug 7 20:41:36 localhost kernel: hdd: packet command error: error=0x54
Aug 7 20:41:36 localhost kernel: hdd: packet command error: status=0x51 { DriveReady SeekComplete Error }
Aug 7 20:41:36 localhost kernel: hdd: packet command error: error=0x54

It seems to be at this fixed rate, e.g. 4 lines/second. Reading the DVD with xine works fine (most of the time), and there are no problems with CD-ROMs or audio CDs.
A few times, I had problems in the middle of playing, in the second half, which makes me think that this could be related with reading on the second layer.

A search on debian-kernel did not show up any relevent info, and my post there was not answered.

What could be going wrong?

Here is some system info:

Debian kernel-image:
Linux blanche 2.6.6-2-686 #1 Wed Jun 16 01:25:38 PDT 2004 i686 GNU/Linux


sudo hdparm -I /dev/hdd

/dev/hdd:

ATAPI CD-ROM, with removable media

Thanks in advance for any help or clue.

debian-kernel is the wrong mailinglist, that's for kernel bugs and kernel packaging, not questions about errors in logfiles etc.

debian-user is the mailinglist you should almost always use, unless you know for sure another mailinglist is more appropriate. debian-user mailinglist has much more people willing to answer questions like this one.

(sorry, I don't know anything about DVD's and DVD-readers, so cannot help with the original question)

Thanks for the info Jeroen, I'm trying on debian-user.

I once had the same problem, which was caused by a buggy IDE cable. In my case, passing
pci=noacpi
to the kernel at boot time solved the problem, and the DVD worked fine.
