So I had to force the shut-down. An user told me to do this commands (log.txt) and since I was in s3 deep (kernel: PM: suspend entry (deep)) I had to do these steps and I confirm the problem disappeared: sudo nano /etc/default/grub then I had to add near GRUB_CMDLINE_LINUX_DEFAULT in the quotes: "mem_sleep_default=s2idle" and since I use radeon I had to add always in the quotes "radeon.dpm=0" Then sudo update-grub I don't know if it is a solution or a workaround and if can be part of a new update of Ubuntu for my machine, but the problem is gone.
