Binary package hint: linux-image-2.6.22-14-generic

I have a Dell laptop with Gutsy on it. I opened the lid to wake it up from its nightly slumber, and bang!

Hi David,

Just curious if the Oops ever reoccurred? If you are interested, 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!

Hi, thanks for looking into this. This oops hasn't reoccurred, so I guess testing the new kernel won't be that much of a help. Since I use this system for my job, I think I'll wait!

Thanks,
Dave

Hi David,

Thanks for the update. I'm going to temporarily close this report against the 'linux' task since you really aren't using the Hardy kernel just yet :) Feel free to reopen it if and when you do upgrade and notice this issue reappear. Also, since it seems like the kernel Oops can't be easily triggered, verifying a fix for the linux-source-2.6.22 kernel might be difficult. I'll triage this against linux-source-2.6.22 but mark it with a low priority. Thanks!

The 18 month support period for Gutsy Gibbon 7.10 has reached its end of life -
http://www.ubuntu.com/news/ubuntu-7.10-eol . As a result, we are closing the
linux-source-2.6.22 kernel task. It would be helpful if you could test the
new Jaunty Jackalope 9.04 release and confirm if this issue remains -
http://www.ubuntu.com/getubuntu/releasenotes/904overview. If the issue still exists with the Jaunty
release, please update this report by changing the Status of the "linux (Ubuntu)"
task from "Incomplete" to "New". Also please be sure to run the command below
which will automatically gather and attach updated debug information to this
report. Thanks in advance.
