Marian639, thank you for reporting this bug and helping make Ubuntu better. Please answer these questions:

* Is this reproducible?
* If so, what specific steps should we take to recreate this bug?
* Could you please confirm this issue exists with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/daily/current/ . If the issue remains, please run the following command in the development 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.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

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'.

Please let us know your results. Thanks in advance.

No, this bug is not reproduced.
Maybe, the error occurred after the connection and disconnection MP3 player. I repeated these steps on my system.
Next, install the kernel 3.4.0-030400rc2_3.4.0-030400rc2.201204072235. There are no errors.
I'll see when this error occurs.
