Comment 2 for bug 235889

Hi Dupond,

As I noted in our IRC converstaion I believe the Ubuntu kernel team recently rebased the upcoming Intrepid Ibex 8.10 kernel with the upstream 2.6.26-rc4 kernel from kernel.org. The Intrepid kernel is currently available for testing in the kernel-ppa (kernel personal package archive) but it looks like the latest version it is still having some build issues so is not yet available. I'll try to update this report when it is ready for testing as well as providing instructions on how to install this newer kernel from the kernel PPA. It would be great if you could test when it's available just to verify this is resolved in the upcoming release. Then we can focus on trying to backport a fix for Hardy.

In the mean time you also mentioned that this is no longer and issue with the upstream 2.6.26-rc4 kernel. It would be great to narrow down the exact patch which would need backporting. You mentioned you tried applying a few patches but were unsuccessful. Another approach you may want to try is a git bisect. That should help narrow down the exact fix. If you are not familiar with doing a git bisect, take a look at the following document:

http://www.kernel.org/doc/local/git-quick.html#bisect

The only tricky part is you will have to switch the meanings of "good" and "bad" when performing the bisect as it tries to isolate the patch which caused a regression rather than the patch which presented the fix. Also in case you didn't pull the upstream kernel source from the git tree, you can get it by doing the following:

git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git

Let us know if you are able to narrow down the patch. Also feel free to ping me again on IRC if I forget to update this report with the instructions of how to install from the kernel-ppa. Thanks.
