Thanks a lot for your analysis. The laptop is slowly dying so this can

I can use that workaround. But it seems that this also prevents me from
suspending the maching into RAM with
PM: Some devices failed to suspend, or early wake event detected

:/

If there is any workaround for that then I would be really happy but
considering the overal state of the machine I suspect this is not the
case.

Thanks again for your great help!
