Do you know if this issue happened in previous version of Ubuntu, or is this a new issue?

Would it be possible for you to test the latest upstream kernel? It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . If possible, please test the latest v3.2-rcN kernel (Not a kernel in the daily directory). Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag(Only that one tag, please leave the other tags). 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.

If this bug is fixed by the mainline kernel, please add the following tag 'kernel-fixed-upstream-KERNEL-VERSION'. For example, if kernel version 3.2-rc1 fixed and issue, the tag would be: 'kernel-fixed-upstream-v3.2-rc1'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. If you believe this bug does not require upstream testing, please add the tag: 'kernel-upstream-testing-not-needed'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Kangarooo, thank you for reporting this and helping make Ubuntu better. If you could also please 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 .

I FOUND bug
needs confirmation
i just tested witch works and since when doest until 4 in row from http://kernel.ubuntu.com/~kernel-ppa/mainline/
Confirm by installing kernels

No this bug using:
[DIR] v2.6.36.4-natty/ 18-Feb-2011 11:34 - http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.36.4-natty/
This bug starts in every next kernel since:
[DIR] v2.6.37-natty/ 05-Jan-2011 11:23 - http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.37-natty/

take files starting with linux-image-*** ending with *** your architecture i386.deb or amd64.deb
then install them and restart in each kernel.
For my Emachines E525 this is how i wrote.
