Judging by the number of different architectures affected, I speculate that bug occurs on a specific class of hardware (specific set of motherboard chipsets?)
I have had this same (or similar?) issue plaguing two of my desktop machines out of three. All have Ubuntu 15.04 currently on all three, all three have similar hardware configurations and the same M/B vendor, yet different motherboards. What I would like to know is, specifically with what hardware components could shutting down become an issue? How would I find out which one I have (maybe, specific entries in output of "lspci", something in the kernel log, etc.)? How do I determine whether two of my machines are suffering from this same bug or a different one? -Thanks -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/987220 Title: [Dell Inspiron 1720] System does not power off reliably when "Shut Down" chosen from GUI Status in The Session Menu: Invalid Status in gnome-session package in Ubuntu: Invalid Status in indicator-session package in Ubuntu: Invalid Status in linux package in Ubuntu: Incomplete Status in upstart package in Ubuntu: Invalid Status in gnome-session source package in Precise: Invalid Status in indicator-session source package in Precise: Invalid Status in linux source package in Precise: Confirmed Status in upstart source package in Precise: Invalid Status in Debian: New Bug description: Shutting down the computer using the menue does not work always correct. It often does not complete turn off the computer. The power LED and the LED of the bluetooth unit remain on. Also the fan is still running and won't stop.
