kernel oops 2.6.24-15-powerpc-smp

i just received another one, also when trying to log into gnome. i am assuming that they are related (if i am wrong i can post a new bug)

reproducable oops that stops gnome starting surely is a high importance.

gnome not starting seems not related. Bug #214574

Hi Sam,

Just curious what was the most recent kernel where this did not occur? May help narrow down which patch is resulting in this issue. Thanks.

i had not noticed it before. it was only beacuse gnome was not starting that i looked in dmesg.

could gnome-session segfaulting cause an oops? (i dont realy understand under what conditions you get and oops and not a panic).

jfyi, I had a very similiar kernel oops today (with latest packages installed), which occured when trying to exit f-spot...

Hi Guys,

Just to see if it makes a difference, care to test the Intrepid Ibex 8.10 kernel? It was most recently rebased with the upstream 2.6.25 kernel and is currently available in the following PPA:

https://edge.launchpad.net/~kernel-ppa/+archive

If you are not familiar with how to install packages from a PPA basically do the following . . .

Create the 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

Then run the command: sudo apt-get update

You should then be able to install the linux-image-2.6.25 kernel package. After you've finished testing you can remove the kernel-ppa.list file and run 'sudo apt-get update' once more. Please let us know your results. Thanks

Bah, my mistake, the PPA doesn't have the ppc flavor available. Sorry.

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.

Per a decision made by the Ubuntu Kernel Team, bugs will longer be assigned to the ubuntu-kernel-team in Launchpad as part of the bug triage process. The ubuntu-kernel-team is being unassigned from this bug report. Refer to https://wiki.ubuntu.com/KernelTeamBugPolicies for more information. Thanks.

Unfortunately it seems this bug is still an issue. Can you confirm this issue exists with the most recent Jaunty Jackalope 9.04 release - http://www.ubuntu.com/news/ubuntu-9.04-desktop . Please let us know your results. Thanks.

This bug report was marked as Incomplete and has not had any updated comments for quite some time. As a result this bug is being closed. Please reopen if this is still an issue in the current Ubuntu release http://www.ubuntu.com/getubuntu/download . Also, please be sure to provide any requested information that may have been missing. To reopen the bug, click on the current status under the Status column and change the status back to "New". Thanks.
