How'zit from South Africa.



I have a dual boot setup for Windows 10/Ubuntu 16 LTS running off of my SSD and a secondary storage 1GB HDD. Windows OS is on the SSD. Ubuntu is on a partition on the 1GB HDD, and Windows 10 uses the rest of the 1GB space of the HDD for storing documents, games, etc. Both OS's were fine until I started experiencing an issue a month or two ago.



PROBLEM:
After selecting the restart/shutdown option in Ubuntu everything goes normal and I get shown the Ubuntu shutdown screen with the white dots beneath the Ubuntu logo. Normally this screen would be followed by a successful reboot/poweroff (I think) but in my case something causes my shutdown process to hang.



I pressed the down arrow key on my keyboard whilst on the shutdown screen and I was shown a bunch of [ OK ] Stopped something messages as the machine proceeds.



The last two messages before it begins to hang:



[ ok ] Stopped Network Manager Wait Online
[ ok ] Stopped Thermal Daemon Service


Then it hangs for a bit, and I get these messages:



[ Time ] Timed out stopping /sys/devices/virtual/block/dm-0
[ Time ] Timed out stopping /dev/disk/by-id/...
[ Time ] Timed out stopping /dev/disk/by-uuid/...
[ Time ] Timed out stopping /dev/disk/by-id/...
[ Time ] Timed out stopping /dev/dm-0


The computer does not recover or do anything else. It just does nothing. The only thing I can do (which I hate doing) is to hold down the power button (on my expensive gaming/developing rig). Powering off like that honestly makes me cry like a baby inside because I have heard that this is really bad for your computer hardware, and that you can corrupt your files/OS.



SOME INFO:
I cannot login with TTY when this problem occurs.



I tried an apt-get update and apt-get upgrade followed by a shutdown/reboot and sometimes nothing will go wrong and the problem seems to be fixed. But, after doing the update and upgrade, If I restart again and then try to power down again the same thing happens.



I have a corsair h100i V2 CPU cooler and I know they do not have any Linux support. But the thing still works and people just use it anyway. I am wondering if this is not causing the Thermal Daemon service to bug out. BUT it gives an [ ok ] message.



I also installed and started using VirtualBox around the same time this started to happen. Could it be related? Those [ Time ] messages seem to deal with a storage device.



Student_23 appreciates your help. Let me know if you need a system log or something, and please I do not want to do a reinstall for Ubuntu that would be a very last resort. Cheers!
