@henrix It works! Thank you very much. The error message used to appear on every boot and now I rebooted 3x and it's ok (I checked dmesg each time).
@oibaf Thanks for explanation, the installation was smooth and so far everything is fine. Here it is different than in your case, because the messages seemed to happen on every boot.
P.S. I won't be using this computer from Monday (for some time), so if you would like me to test sth, please write today (2013-11-03).
