I'm not sure when this starts to happen, but it was some 4-5 weeks ago. Normally, I do system updates on a regularly basis every time I'm using the machine. Before it works quite well always. I guess, it was with the August update of the kernel, when it starts to happening. I attached the latest apt history files about that.
