[Bug 1335599] Re: computer freezes while poweroff

 

I have the same bug when I'm not connected into the desktop environment
(just the lightdm greater). I login into a tty console and execute "sudo
poweroff". Same result.

Title:
  computer freezes while poweroff

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Using Lubuntu, I click on the "logout" button from the desktop menu
  and choose to poweroff the computer. Then I see the plymouth feedback
  (lubuntu written besides dots which are changing their color while the
  shutdown). Finally, I get a black screen but the computer still run
  for minutes. I have to force the poweroff with a long pression on the
  power button of my laptop.

  Later I see in /var/log/syslog :
