Suspend / halt not working anymore after a Software Updater launch

According to the issue mentionned here: https://trisquel.info/fr/forum/suspend-halt-not-working-anymore-after-software-updater-launch there is a problem with the suspend / halt functionality since I have updated my system.

Around end February / beginning of March I performed a Software Updater launch, in order to update my Trisquel OS.

$ cat /proc/version Linux version 4.4.0-142-lowlatency (name at domain) (gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.10) ) #168+8.0trisquel2 SMP PREEMPT Tue Feb 5 02:09:39 UTC 2019 $

The problem now is that my laptop gets frozen after trying to suspend it or performing the command: shutdown -H The system seems to start to suspend but we get a black screen (can not see when is really happening) and after a while (few tens of minutes) the computer is off: maybe because the computer gets too warm and brutally stops.

Can we fix this annoying issue?

For information: I have now updated to the actual "4.4.0-143-lowlatency #169+8.0trisquel2" release and the problem is still on going...

Thank you for your kind support.
