Bug Description
My wife is a DVD maven, and has been watching DVDs using an AMD64x2 shuttle running Jaunty Mythbuntu. After watching a DVD for some time, it the player will about somewhere near the end of the DVD, usually with the last 2 chapters being unplayable.
Using Ubuntu linux-image-

This has happened repeatedly. I have swapped the DVD writer out, and it still happens.
Here is debug information:

This bug occurs with both linux-image-
Yes, I forgot to add that rebooting fixes the problem (I should look at unloading/reloading DVD media kernel modules) and you can play past the point where xine gave up. When xine gives up, mounting the DVD and reading the last VOB files on the media results in the above kernel messages.
and I reflashed the Pioneer DVD writer to latest firmware version to see if that would help.
It is looking like a serious problem in the 2.6.x kernel source somewhere?
