Since a recent update (not sure which, sorry) I have been unable to perform a clean shutdown or reboot - it just sits at a black screen doing nothing (apparently).
Steps to reproduce:
1) Boot up into Ubuntu
2) Shutdown or Reboot using any available command (I've tried command line, and the power options from the power indicator)
3) Computer ends up on a black screen which needs me to hold down the power button for 8 seconds to switch off the system
I'm not sure what other debugging information you need for this. What can I provide for you?

Stephen Rees-Carter, thank you for reporting this and helping make Ubuntu better. This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please capture the oops following https:/
If it remains an issue, could you run the following command from a Terminal (Applications-
apport-collect -p linux <replace-
Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https:/
Thanks in advance.
