I am using Ubuntu 14.04. When it shuts down, it would print out many error messages, and hang.

1Your screenshot is hard to read, did you take the picture once it was stuck or while it was printing errors?!– Alexis WilkeFeb 6, 2016 at 21:41

@AlexisWilke It's running so fast that I cannot capture a stable image.– Jill CloverFeb 6, 2016 at 22:25

Ah, I see, it hangs in a forever loop... At times Ctrl-S still works, but I would be surprised because by then it probably has no console functionality anymore.– Alexis WilkeFeb 6, 2016 at 22:30

The one reason for my shutdown to hang is because my nVidea video board driver will get blocked, although when that happens I do not see any messages.
In any event, here it says that it has a problem with PCIe Port 0000:00:1c.6 so we would need to know what's connected on that port to get a better feel of what the kernel does not like.
You can see what it is with an lspci command in your console after a reboot. In my case, it is an Intel Bridge:
00:1c.6 PCI bridge: Intel Corporation 5 Series/3400 Series Chipset PCI Express Root Port 7 (rev 06)
It seems to say that it is the same on your computer (i.e. it says it is a bus). It could be that you have a video board that it does not like...

This answer is very vague. As you do not really provide any sure solution, in my opinion this would have better been a comment only. Or you reword it to be more definite.– Byte Commander ♦Feb 6, 2016 at 22:13

If we can get info on his hardware that matches what I'm saying, we're possibly on the right track. We would need the output of his
lspci. That being said, there are times when a comment is ill adapted to give clear examples of output or commands, in my point of view. Feb 6, 2016 at 22:32
