Thanks for reporting this bug and any supporting documentation.

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.

I tried with the 2.6.35-02063507-generic that is the mainline corrispondent of my kernel and the problem occurred.

Now I'm going to try the last kernel of the 2.6.35 serie and after the latest mainline kernel (if the problem continue to occur).

Bug affect also 2.6.35-02063508-generic

Now I can choose to try:
2.6.36-020636-generic

or directly the latest (in rc): 2.6.37

What is better to do?

I tried the 2.6.36-02-06-36 kernel and when I disconnected the adaptor the computer freezed the same.

I wait more help with all the named kernels installed.

Just to test I installed Debian squeeze and the experimental 2.6.36 debian flavoured kernel and I have no freeze.

The trouble is probabily in the package pm-utils, it continue to happen in the other version of ubuntu but it suddendly disappear if I manually install the version 1.3 instead of the 1.4.

aleritty, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

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

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

Also, could you please test the latest upstream kernel available (not the daily folder, but the one all the way at the bottom) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.12

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.
