[Bug 562092] Re: Cdrom drive not recognized automatically
Hi again, Reporting back after a couple of weeks since switching back to 9.10 and I have not had a single instance of my optical drives failing to stay mounted. If there is anyone out there who needs any further information from me, or needs me to do any special testing, please let me know.

[Bug 562092] Re: Cdrom drive not recognized automatically
Hello, I have finished the roll back to 9.10 and the problem is completely gone (again). I played a DVD for 12 hours without any issues. I am not ready to call it fixed for another couple of days. I will check back after a few days.

[Bug 562092] Re: Cdrom drive not recognized automatically
Hello again all, The 'acpi=off' fix that I listed above as a fix is no good... I had several days of flawless operation, but now the problem is back... I am not sure why I was able to work properly for a couple of days, but clearly this particular fix was not it. It may have been a coincidence or just dumb luck... Anyway, I am rolling back to 9.10 right now. I will repost with the results later.

Hi Fabio, Do you have a wired keyboard/mouse that you can use to test it out. If we can get you and a couple of other people to verify, then we can resubmit to the ACPI team..

[Bug 562092] Re: Cdrom drive not recognized automatically
OK! I have found a fix for this problem!!! (actually found the fix in one of the fedora forums) Let me first clearly define the problem that I am fixing: Conditions: 1. CD/DVD/CDR/CDRW disks "unmount" themselves shortly after mounting. 2. dmesg reports the following - VFS: busy inodes on changed media or resized disk sr0 3. I currently have no entries for either drive in /etc/fstab... The problem was exactly the same when I had the "/dev/sr0 /media/cdrom0 udf,iso9660 noauto,users 0 0" or similar lines in /etc/fstab. 4. Once one of the drives "unmounted", only a reboot would allow me to mount again. 5. All other devices and drives mount normally (and stay mounted with no issues).. 6. My relevant hardware is: Asus P5N-e motherboard, cdrom:0 :: description: DVD-RAM writer :: product: CD/DVDW SH-S182D cdrom:1 :: description: DVD-RAM writer :: product: CD/DVDW SH-S182D Both drives are run off the secondary ide channel. 7. The hardware (motherboard and drives) is guranteed to be functional. I could not get either drive to fail in WindowsXP during overnight testing. FIX:: Add "acpi=off" to the kernel load line in /boot/grub/grub.cfg then reboot... For example: linux /boot/vmlinuz-2.6.32-24-generic root=UUID=c82dfc28-0bcf-48a6-995f-b61464bcf056 ro quiet splash acpi=off I have gone through 2 days of stress testing the drives and neither has unmounted AND there are no more errors in dmesg... TO DO: 1. Get more users to confirm this fix. 2. Submit the data to the ACPI team if it looks like the fix is repeatable.

I also upgraded to 2.6.32-24-generic and still have the problem. I refuse to change hardware for this issue because both of my drives are identical and they both work perfectly using windowsXP. fstab tinkering has shown no promise. -- [Lucid] cdrom drive not recognized automatically https://bugs.launchpad.net/bugs/562092 You received this bug notification because you are a member of Ubuntu Bugs, which is a bug assignee. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 562092] Re: [Lucid] cdrom drive not recognized automatically
I am also having a problem after upgrading to 10.04. I can not mount cd/dvd's except under the following condition: immediately after a reboot, and even then the disks will only stay mounted for a while before I start getting the "Buffer I/O error on device sr1, logical block 297861". I have an ASUS P5N-E SLI motherboard. Several people have suggested that there may be a correlation with ASUS motherboards. What I have tried... 1. Removing / adding / fiddling with fstab entries. 2. Reinstall entire operating system. 3. Changed order of boot devices in BIOS (from suggestion in the forums) 4. Ruled out hardware (drives working fine in WindowsXP). I have a dual boot setup. Things to do: Roll back to Karmic and verify that the drives start working again... *-cdrom:0 description: DVD-RAM writer physical id: 0.0.0 bus info: s...@5:0.0.0 logical name: /dev/cdrom1 logical name: /dev/cdrw1 logical name: /dev/dvd1 logical name: /dev/dvdrw1 logical name: /dev/scd0 logical name: /dev/sr0 capabilities: audio cd-r cd-rw dvd dvd-r dvd-ram configuration: status=open *-cdrom:1 description: DVD-RAM writer physical id: 0.1.0 bus info: s...@5:0.1.0 logical name: /dev/cdrom logical name: /dev/cdrw logical name: /dev/dvd logical name: /dev/dvdrw logical name: /dev/scd1 logical name: /dev/sr1 capabilities: audio cd-r cd-rw dvd dvd-r dvd-ram configuration: status=open -- [Lucid] cdrom drive not recognized automatically https://bugs.launchpad.net/bugs/562092 You received this bug notification because you are a member of Ubuntu Bugs, which is a bug assignee. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
