Bug Description
While the preinstalled Ubuntu Jaunty runs fine (well done, Dell!) on my Latitude 2100, I experience random hard kernel panics with Ubuntu 9.10.
It seems the problem has something to do with network activity. I experience it on:
- Firefox browsing
- copying files from/to a Samba share with Nautilus
- even on file transfers through sshfs and scp.
Unfortunately, the bug is semi-reproducable in such way that e.g. a scp fails in about one of five cases.
I neither know which part of the system is responsible for these panics nor how to identify the error, since the system just freezes and no information is printed to the console or /var/log/messages. As I have KMS enabled, the last thing displayed is my mouse cursor inside an empty TTY console (which is very interesting, too). Disabling KMS did not bring up any further information.
Does anyone have a suggestion how to identify the error?

Please run the following command which will automatically gather and attach general kernel debug information:
apport-collect -p linux 412704
Unfortunately without seeing the output of the kernel panic, it'll be hard to nail down what's going wrong here. You may want to try the latest mainline kernel build a well just to verify if this issue exists with the upstream kernel. See https:/ /wiki.ubuntu. com/KernelTeam/ MainlineBuilds . Let us know your results. Thanks.
