Sorry that "again" is a bit misleading. I Copied it from here: 
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=7592b79ba4a9

I actually only tested the direct predecessor of this Notebook on older kernels: 
https://bugzilla.kernel.org/show_bug.cgi?id=216698

I suspected that it's the same issue and since the same fix worked I now even 
more believe so, but I actually never tested a kernel before the breaking change.
