I can support this bug report. For my (very new) computer details see attachment (lshw.txt) I currently use Linux xxxxx 3.13.0-35-generic #62-Ubuntu SMP Fri Aug 15 01:58:42 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
In /etc/default/grub I have the line: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=off" Symptoms: without the "acpi=off" parameter the computer used to reboot repeatedly. With "acpi=off" it boots OK, but reboots spontaneously after shutdown, and the computer must be powered off using the power switch. Trying the most recent upstream kernel ( 3.12.28, I guess compiled 9th of september) the computer boots OK, even without "acpi=off" and but during shutdown, after showing 2 red dots of the 5, first time. The computer has to be switched off using the power button. So another behaviour, but still it is not OK. I also tried a LiveCD with Ubuntu 12.04.1 (Precise), this was quite OK (only no sound, on this very new hardware) Same with LiveDVD with Ubuntu 12.4.5 (Precise, the latest), this behaved same as the 14.4.1 LiveDVD So the bug entered somewher between Ubuntu 12.04.1 and 12.04.5 Hope this helps, adding 50% to the people affected ...
