Comment 114 for bug 1419355

Hi again!

I have made some reasearch and it seems to work now. Every user that have ASRock motherboard and expirience this issue I would like to go to UEFI settings and then Advanced->ACPI Configuration. Please enable two options:
1. USB Keyboard/Remote Power On
2. USB Mouse Power On
Save changes and reboot by pressing F10.

Before you do this, make sure that you have installed the newest NVIDIA driver from NVIDIA website. I did not test driver from Ubuntu repo or xedgers ppa (including nouveau). I am making fresh install of Ubuntu now to make sure that my solution works fine.

Additional info:

My solution works well with kernel 3.13.0-54-generic and 3.16.0-28 as well.

I had three problems:
1. My machine reboots few seconds after shutdown.
2. Computer goes power off when I pressing power button but he wake up every time when I attach any device to any USB 3.0 port. He stay power off when I make same test with all USB 2.0 ports.
3. My Dell KM714 wireless mouse and keyboard do not work until Ubuntu starting initialisation. I could not enter to UEFI settings or choose others entry in Grub menu.

Solution which I have described upper solve all this issues.

To kernel developers: If you need any additional info I can assure them.

I have made few more test:
My solution fix this bug on Ubuntu 14.10 and Fedora 20/21(the newest 3.17 kernel version) as well.

Sorry for my bad english but I hope you will understand me. Somehow I had to share with my fix of this issue.
