Today, kernel 4.4.0-83 its booting fine (and it doesn't crash/hang on boot).
(And yesterday, I did many reboots using the laptop power-on button, and it crashed every time, after the package upgrades).
I run ubuntu-bug and chose "distribution upgrade" category (what else ?), but it gave back no bug report number, so that I can add an explanation to what is being reported.

Next time it happens, I will try to follow /wiki.ubuntu. com/Kernel/ CrashdumpRecipe #Crash_ kernel_ fails_to_ load:_Hang

(but it seems a bit complicated).
(and I will run a memory check first...)
Thank you for the followup.
