After running for some time, the cdrom driver becomes unresponsive

[Bryan Donlan]

Binary package hint: linux-source-2.6.22

After my laptop (Compaq Presario v6000z) runs for an extended time (several hours), its cdrom driver fails to respond - that is, if an application attempts to use it, it becomes stuck in the unkillable D state. Rebuilding the kernel with all non-libata drivers disabled is a workaround which enables the cdrom to be usable.

I will reboot into a libata kernel this weekend and try to collect the (nonfatal) message it emits there.

Thanks Bryan. I'm just tagging this as 'hardy-kernel-candidate' to make sure we carry this report through to the upcoming Hardy Heron kernel. Please keep us posted with the additional information you gather this weekend. Thanks!

The Hardy Heron kernel was recently uploaded for testing. We'd really appreciate it if you could try testing with this newer kernel and verify if this issue still exists. Unfortunately, the Hardy Heron Alpha1 LiveCD was released with the older 2.6.22 kernel. You'll have to manually install the newer Hardy Heron kernel in order to test. This should not be the case for Alpha2. However, here are the instructions to install (if you choose to do so):

1) edit the file /etc/apt/sources.list and add the following line:

deb http://archive.ubuntu.com/ubuntu hardy main restricted

2) sudo apt-get update
3) sudo apt-get install linux-image-2.6.24-1-generic
4) reboot and select the new kernel from the grub menu

After you've tested, please feel free to revert back - ie boot into the old kernel, sudo apt-get remove linux-image-2.6.24-1-generic, and remove the line from /etc/apt/sources.list . Please update this report with your results. Thanks in advance!

This bug report is being closed because we received no reponse to the last inquiry for information. Please reopen it if this is still an issue in the current Ubuntu release. To reopen the bug report you can click on the current status, under the Status column, and change the Status back to "New". Also note, the Hardy Heron Alpha4 series was recently released which contains an updated version of the kernel. You can download and try the new Hardy Heron Alpha release from http://cdimage.ubuntu.com/releases/hardy/ . You should be able to then test the new kernel via the LiveCD rather than needing to manually install. If you can, please verify if this bug still exists or not and report back your results. General information regarding the release can also be found here: http://www.ubuntu.com/testing/ . Thanks.
