I've tried the latest upstream kernel, as it is described in the link above. Unfortunately the mainline kernel does not fix this bug.
I don't know if it is important, but with the upstream kernel I had no wlan - even when I boot the 3.13 kernel. After I remove the upstream kernel the wlan works again.

Thank you for your efforts.
