Hello guys,
I can't shutdown my laptop. It hangs at the very last step of shutdown I think. I have disabled "quite splash" so I see what's going on during shutdown. The last message is always "reboot: power down", when I try with Linux. I also tried shutting down from a FreeBSD-Live-System, it worked one time, but after that it didn't work again.
The debug-shell is no use, because at the freeze point I can't type in commands. I also tried to shutdown with the following terminal commands:
Code:
sudo shutdown now
sudo shutdown -P now
sudo shutdown -h now
poweroff
sudo poweroff -f
sudo halt -p
All of them had the effect as describe above except the command
Code:
sudo poweroff -f
After I typed the command, I authenticated and following messages appeared: "Powering off...". At this point it freezed. I could still see the desktop and every visible window, but I couldn't perform any actions; not even keyboard shortcuts worked. When I tried the key combination "Alt + SysRq + R + E + I + S + U + O" (see https://en.wikipedia.org/wiki/Magic_SysRq_key) the same thing happened. It also did not help to change 'GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"' in /etc/default/grub to 'GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force"' and run
Code:
sudo update-grub
I also tried several other kernel parameters, none of them worked so far. If you have a idea which one could help, please tell me
Once the following command combo did work:
Code:
sudo swapoff -a && systemctl poweroff"
but then I reinstalled Ubuntu and now it doesn't work any more. When I wake up the laptop, a black screen appears with some error messages, but only for a very short time so I can't make a photo of it.I tried once and the text was unreadable.
I have the latest BIOS and my Computer model is MSI PX60 2QD. Here the hardware specifications:
to this post. I use UEFI and secure boot is disabled. I tried to install the packages "intel-microcode" and "firmware-linux", it didn't help. I tried the following instantly after I tried to shutdown:
Code:
$ sudo journalctl -k -r

Aug 21 22:39:56 MSI kernel: ACPI: NMI not connected to LINT 1!

Could this somehow be related with my problem?
Is someone of you able to help me?

Reason: Updating information
Always "reboot"??? Even if you told it to shut down?
Anyhow, it hangs at that point, right?
It sounds like an ACPI issue to me (according to your last post you already suspect that too?).
The solution is to add some magic to your kernel command line. You have to search what might help, you ight need to try a few times. When you find what works we can help you make it permanent.
the URL mentioned in post #86 (https://www.msi.com/support/nb/PX60-2QD.html#down-bios) leads nowhere. I don't understand the last line of this post: "EDIT: Someone on the kernel bug tracker for this extracted the microcode update for 5700hq CPUs like the MSI update, if you want to try loading it at boot time: https://bugzilla.kernel.org/show_bug.cgi?id=103351 http://benjam.info/downloads/5700hq-ucode.tar.gz" Does that mean, I shall install the linked kernel in order to fix it?
Always "reboot"??? Even if you told it to shut down?
Yes and no. This message appears only when I tell it to shutdown.

Yes, I also suspect it, but I'm not sure.

I already tried several kernel parameters and none of them worked. acpi=force for example had a very bad effect: it prevented me from booting.
