Bug Description

Immediately after install of Maverick on Dell Inspiron 9100 the networking has become very unstable. When an application attempts to establish a network connection (eg. Firefox connect to Google) the system intermittently hangs. No mouse, no keyboard, no activity of any kind. The display freezes. The only recourse is to push the power button until power is shut off.

This is reproducible about 75% of the time by simply launching Firefox and then attempting any internet connection. It also occurs when opening system utilities that use networking, for example Synaptic Package Manager.

This did not occur, at all, before the upgrade to Maverick. It began immediately after the upgrade. The last good kernel was 2.6.32-25-generic. The kernel that's causing the problems is 2.6.35-22-generic.

Forgot to add: When I boot the old kernel, 2.6.32.25-generic, the problem goes away even though the rest of the system is 'Maverick'.

Today I upgraded Firefox to 3.6.12 and the kernel to 2.6.35-23.36. The problem persists. The system simply won't run on this kernel. I have to boot the old 2.6.32.25 to be able to even get this message to you.

As before, the system hangs -- no keyboard, no mouse, no interactivity in any way. CPU seems to go full tilt based on sound of the fans. The system will run for a few seconds to at most two minutes after boot, then hangs. The problem seems to crash when Firefox and other internet apps are in use.

Warren, thank you for reporting this and helping make Ubuntu better. Maverick reached EOL on April 2012.
Please see this document for currently supported Ubuntu releases:
https://wiki.ubuntu.com/Releases

We were wondering if this is still an issue in a supported release? If so, can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command in a supported release from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux <replace-with-bug-number>

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.
