ACPI - libata IDE regression 2.6.15-20 => 2.6.15-21

[Michal Pokrywka]

Binary package hint: linux-source-2.6.15

Dapper flight 6 started on my notebook (Asus W3V) without problems.
Recently I downloaded kubuntu flight 7 and somehow managed to
install it on hdd - live cd paused on initrd, but resumed after a minute or two.
I installed kubuntu but system failed to boot after restart.
Flight 7 boots with acpi=off kernel parameter, I also copied
kernel from Flight 6 (2.6.15-20-386) and it boots without problems.
Dmesg, lspci, dmidecode attached.
Thanks to featurefull initrd I managed to save "dmesg" from
failed boot to pendrive - also attached.

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu kernel bugs need to be reported against the "linux" kernel package. We are automatically migrating this linux-source-2.6.15 kernel bug to the new "linux" package. We appreciate your patience and understanding as we make this transition. Also, if you would be interested in testing the upcoming Intrepid Ibex 8.10 release, it is available at http://www.ubuntu.com/testing . Please let us know your results. Thanks!

This bug does not affect Feisty and newer kernels. I am not familiar with launchpad's bug handling - I think this bug should be only assigned to dapper's kernel.

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

Dapper support has run out, and this bug should be fixed in newer versions of Ubuntu.
