First of all, many thanks for your help on this.

I tried to apply the fix to the 3.10.16 sources, as I would like to stay with the long-term line. Unfortunately it does not apply, as there are a lot of dependencies on other patches.

Do you think there will be a fix for the long-time 3.10 kernel line? Or can you guide me on how to apply this fix to the long-term kernel?

Best regards,
Peter
