I also have this problem. IRQPOLL didn't work for me too.
It is so sad I can read burned DVDs everywhere but not on device that burned them :-( At first I thought burner died, bought new one and same thing started to happen within few months. Last week I did fresh install of Gutsy Tribe 5 and problem is still there. After putting burned DVD in drive, /var/log/messages shows output: Sep 11 21:39:09 willow kernel: [ 141.700000] attempt to access beyond end of device Sep 11 21:39:09 willow kernel: [ 141.700000] hdc: rw=0, want=68, limit=4 Sep 11 21:39:09 willow kernel: [ 141.708000] attempt to access beyond end of device Sep 11 21:39:09 willow kernel: [ 141.708000] hdc: rw=0, want=1252, limit=4 Sep 11 21:39:09 willow kernel: [ 141.708000] attempt to access beyond end of device Sep 11 21:39:09 willow kernel: [ 141.708000] hdc: rw=0, want=1028, limit=4 Sep 11 21:39:09 willow kernel: [ 141.708000] UDF-fs: No partition found (1) Sep 11 21:39:09 willow kernel: [ 141.732000] attempt to access beyond end of device Sep 11 21:39:09 willow kernel: [ 141.732000] hdc: rw=0, want=68, limit=4 Sep 11 21:39:09 willow kernel: [ 141.732000] isofs_fill_super: bread failed, dev=hdc, iso_blknum=16, block=16 Please, please fix this bug as linux not being able to read media, that previously burned, is a serious bug. -- CDROM drive no longer working, unable to mount. https://bugs.launchpad.net/bugs/94119 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
