It unfortunately seems that this bug report has gotten a bit bloated and hard to follow. There are comments here that this is resolved for some, there are workarounds for others, and then more comments that the issue still exists. It's rather difficult for the kernel team to pick out the relevant pieces of information to help debug the issue.
Note that it's helpful to the kernel team if bug reports target a specific bug against a specific set of hardware. Even though you may be experiencing the same symptom reported here, it will often require fixes in different drivers based on the hardware you are using. Because of this, if you have hardware which differs from the original bug reporter I'd encourage you to please open a new bug report. We can easily mark bugs as duplicates later on if necessary. Also please be sure to include the appropriate debugging information as outlined here: https://wiki.ubuntu.com/KernelTeamBugPolicies . I apologize for any inconvenience this may cause but appreciate your cooperation.
Finally, I'd like to hear feedback from Valkai who is the original bug reporter. Valkai, does this issue still exist for you in kernel released in Hardy final (kernel 2.6.24-16.30). What about the 2.6.24-17 kernel in hardy-proposed? To test the kernel in hardy-proposed, create the file /etc/apt/sources.list.d/hardy-proposed.list to contain the following two lines:
deb http://archive.ubuntu.com/ubuntu/ hardy-proposed main
deb-src http://archive.ubuntu.com/ubuntu/ hardy-proposed main
Then run the command 'sudo apt-get update'. You should then be able to install the linux-image-2.6.24-17 proposed kernel.
If the issue still persists with the 2.6.24-17 kernel, would you be willing to then test the Intrepid Ibex 8.10 kernel which is currently being pulled together and was most recently rebased with the upstream 2.6.25 kernel. It is available for testing at the following PPA: https://edge.launchpad.net/~kernel-ppa/+archive . The steps to test from a PPA are similar to testing from hardy-proposed except create a file /etc/apt/sources.list.d/kernel-ppa.list to include the following two lines:
deb http://ppa.launchpad.net/kernel-ppa/ubuntu hardy main
deb-src http://ppa.launchpad.net/kernel-ppa/ubuntu hardy main
Run 'sudo apt-get update' as you did before. You should then be able to install the linux-image-2.6.25 kernel. Once you've finished testing please feel free to remove the files you created in /etc/apt/source.list.d/ and run 'sudo apt-get update' once more to restore your system to its original state. Please let us know your results. We'd appreciate hearing back from you. Thanks Again.
