Public bug reported:

After upgrading to 16.04, my computer goes to sleep during the boot process, 
shortly after I entered the passphrase to unlock my LVM. When I wake it up, I’m 
at the graphical login prompt. I type my user password, press enter and it goes 
to sleep again. When I wake it up, I’m in my working Lubuntu desktop. This 
happens every time I boot. And it’s quite annoying.
Please tell me which additional information I can provide to help fix this bug.
