[SOLVED]Reboot/shutdown doesn't work (HP laptop)

Hello people,
I have 2 big problems, the first one is that booting only works in about 60-70% of times (when it doesn't work, it gets stuck and I can't enter any command). I mention this one because it may have to do with the second one, but I am not sure.
The second one, and the one I'd like to solve with you guys in this thread, is that rebooting/shutdown doesn't work. For example "sudo reboot" or "systemctl reboot" or "systemctl poweroff" or "sudo shutdown" intiate systemd to close modules/processes but then just before powering off, the computer gets frozen. (yes I waited more than 5 minutes and nothing happens).
According to this page: https://wiki.freedesktop.org/www/Softwa … Debugging/, the command

sync && poweroff -f

should tell me whether it is a systemd or kernel "bug". I tried that command when I was on the lxde desktop environment, what it did was freezing the computer (mouse cursor wouldn't move).
I've taken a photo about what happens when I usually type "systemctl poweroff", at the moment it gets frozen. Here it is: http://i.imgur.com/k0PGluq.jpg
Thus, apparently the problem is NOT related to systemd.

I also tried a live CD version of Lubuntu (so it has another kernel, probably 3.16 or 3.18) and it had the same problem.

However I dual boot with Windows 8.1 and reboot/shutdown work properly so it isn't a hardware problem.
Worth mentioning is that the hardware is a HP laptop, the exact model and specs can be found there: http://support.hp.com/us-en/document/c04439109.

Thanks for any tip to solve the problem(s) or diagnose it.

man-db cache can take a while to update. Disable it and see if you can boot or some issues persist.

Well it's a fresh install, I have almost no program and if I understand well this is ran only once per day while my booting /shutdown problems are permanent. Thus I highly doubt that this is the culprit.
But ok, I'll mask the service.

Edit: Suspend doesn't work either. The screen turns black but the keyboard lights are on and the fans are on.

Edit: The booting problem is definitely not related to mandb. The system hangs right after the word "blocks" in the screenshot in the 1st post of this thread.

I dual boot with Windows 8.1

Try disabling "fast startup" in Windows.

Will your system reboot properly if you use either of these kernel parameters:

reboot=bios
reboot=acpi

Have you tried:

systemctl poweroff -i
systemctl reboot -i

Thank you. Unfortunately none of this worked (I had fast start up disabled), I took care to generate the grub.cfg file after each change.

Instead, however, what worked for me is:

echo "blacklist dw_dmac" | sudo tee -a /etc/modprobe.d/blacklist.conf
echo "blacklist dw_dmac_core" | sudo tee -a /etc/modprobe.d/blacklist.conf

I found out the answer at https://askubuntu.com/questions/580666/ … ilion-x360.

It seems a very common problems with HP laptops so I hope that this helps hundreds of people.

echo "blacklist dw_dmac_core" | sudo tee -a /etc/modprobe.d/blacklist.conf

sudo tee -a /etc/modprobe.d/blacklist.conf <<< "blacklist dw_dmac"
sudo tee -a /etc/modprobe.d/blacklist.conf <<< "blacklist dw_dmac_core"

Or perhaps:

# echo -e "blacklist dw_dmac\nblacklist dw_dmac_core" >> /etc/modprobe.d/blacklist.conf

(Sorry)
