The relevant code should match mainline 1:1 there unless I'm > mistaken. Arjan ? I'm having similar problems running vanilla 2.6.7 with Debian-amd64 on an Athlon 64 using a Philips DVDR824P. It refuses to read some of my dvd+r discs to the end, while some may even refuse to mount. In both cases the errors are of the "attempting to access beyond end of device" type. Interestingly the same discs on my laptop with 2.6.7 and an LG GCA-4040N dvd+rw writer read fine. After some time (and some cd burns later) one of the discs which used to give errors on the Philips writer started to read fine again, which left me a bit confused. Sorry for not being too detailed about system configuration at this time. If you have interest in this, I can give more detailed system info and try to report as soon as this happens again with the exact error messages. Unfortunately I have not yet managed to create a test iso image or similar which would reproduce the problem reliably, but I can add that something similar also happenned with cdroms.
