**My Problem:**

Ubuntu doesn't shutdown/reboot and is stuck on line like:

`/dev/sda: clean, xxx/xxx files, xxx/xxx blocks` 

and sometimes with several similiar lines and sometimes with 

`recovering journal` 

at the top.

At first the problem was that it stucked with 

`CPU#X stucked for XXs` 

but I've managed it somehow from the list below :)

**What's done:**

1. sudo update && upgrade && dist-upgrade` and loaded updates with ubuntu-software-center.
2. `sudo purge nvidia*` and `sudo apt-get install nvidia-361`
3. switched to Intel HD card in "Nvidia settings" (nvidia prime).
4. fixed grub with `GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force`
5. (tried `apm=power_off` and `acpi=noirq` too).(tried `apm=power_off` and `acpi=noirq` too).
6. disabled `usb 3.0 legacy mode`.
7. disabled swap partition with `sudo swapoff /dev/sdaX` and commented it's entry in fstab.
8. smth in `/etc/modules` I've forgotten..

**My hardware:**

MSI GE62 6QD (Laptop);  

i5 6300HQ (4 cores);  

intel hd530 + Nvidia gtx 960;  

16gb RAM DDR4;  

Windows 10 UEFI on default 1TB HDD;  

SSD Intel 540s via M.2 (UBUNTU UEFI);  

Dualboot via bootmenu (F11) yet..  

I just didn't update kernel manually, but I can try if you'll help me a little with right way of doing it.

Installation process didn't go easy too. It got stucked on first "preparing" screen with "Ubuntu" logo. Solved with `nomodeset` in boot params.
I've tried hackintosh OSX El Capitan on this M.2 SSD and it worked rather fine (of course not excellent).

I'm very sorry, cause I'm not a guru in kernels/terminal/bootargs/etc, so I tried almost every solution that helped somebody..

Hope for your help. I need my lovely OS working well on my new monster-laptop.
