Public bug reported:
This is a fresh install of Ubuntu 18.04.6 on Dell Latitude 7390.
The system is non-recoverable after it goes into sleep. Or after the
screen is locked by the user and after it fades to complete black.
System becomes unresponsive, no mouse or keypress will get the system
back on to work.
If the systemctl suspend is issued, the system will not wake up again.
Hard reset is needed.
If Ubuntu 18.04.6 is booted from live USB, the same is happening.
Sometimes, when the system is rendered unresponsive as a result of any
of the above, the power led is sending the message of "processor
failure" (2 x amber blinks followed by 1 x white blink).
Any help is greatly appreciated! I will keep the system as is, without
applying any updates for now.
