Comparing various logs of 4.8.0 vs 4.9.0 I didn't spot significant 
differences. As a test, I also tried to install the proprietary nvidia 
drivers and CPU microcode update packages, but things didn't change.

Thanks to an off-list exchange I managed to boot 4.9.0 in normal mode by 
deactivating the discrete graphic card (Nvidia Optimus) from BIOS. The 
integrated card is good enough for me anyway.

Best,
Francesco
