I'm dropping this information here, in case it turns out useful for you. I saw you marked this as confirmed, so I tried to reproduce it again, with the current Dapper kernel (2.6.15-28.55) - this time without success. I only tried one known faulty disc though, (but the same as last time, IIRC,) so I can't be sure if something else would be needed to trigger the bug again.
My other (newer) drive performed without fault, and the drive that had previously experienced the trouble announced this in the logs: "cdrom: dropping to single frame dma" instead of "cdrom: dropping to old style cdda ...". In sum, this time the drive didn't drop to "old style cdda", which I think contributed to the issue originally. (With "single frame dma", if I tried to access the disk with two different programs, lsof would report both trying to access it, but neither program seemed able to read any data - once I quit one of these, the other started receiving data.) I expect the issue with the flood of error messages would re-emerge if the drive again dropped to "old style cdda" for some reason. I also can't tell if the problem can still occur on other hardware - possibly yes. -- System logs fill with cdrom errors (1 GB per 20 minutes) https://bugs.launchpad.net/bugs/64548 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
