Comment 1 for bug 404472

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?

Hardware is a Shuttle SN95G5 with Nvidia Nforce 3 chipset, 2GB RAM, and an AMD64x2 4400+ CPU.
