hello, few years ago I noticed annoying bug on Linux, when I was copying photos from old DVDs I realized that not all files were copied correctly, there were errors on last files on DVD, you could say "well that happens, DVD are faulty", but that's not the real issue
when the problem appears it happens on each DVD I am trying to copy, last files on each disk have errors.... ...until I reboot Linux, then there are no errors at all and full DVD is copied correctly. Now I needed some files from DVDs and I realized the problem still exists. After at least three years. I verified that reboot helps and I also noticed the problem doesn't exist on Windows 7. And looks like I wasn't only one who found this: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/404472 Problem was reported in 2009 on 2.6.28 and closed in 2012. But I noticed it in last days. my system is: Linux version 3.6.8-1-ARCH (tobias@T-POWA-LX) (gcc version 4.7.2 (GCC) ) #1 SMP PREEMPT Mon Nov 26 22:10:40 CET 2012 dmesg: [ 4017.384169] attempt to access beyond end of device [ 4017.384171] sr0: rw=0, want=8511124, limit=8433216 [ 4017.384174] attempt to access beyond end of device [ 4017.384175] sr0: rw=0, want=8510876, limit=8433216 I suspect that people just stopped using CDs and DVDs and that's why nobody was looking on this problem, or maybe the first though was always "that DVD is broken, trash it". Is there more information I could give you about this issue? Or could you point me to any ways I could debug it? It's fully reproducible on my system. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
