System freezes when shutdown

# uname -a
Linux halo 4.0.1-1-ARCH #1 SMP PREEMPT Wed Apr 29 12:15:20 CEST 2015 i686 GNU/Linux
# cat /sys/kernel/debug/vgaswitcheroo/switch 
0:DIS-Audio: :Off:0000:01:00.1
1:IGD:+:Pwr:0000:00:02.0
2:DIS: :DynOff:0000:01:00.0

It seems that the problem occurred when I updated the kernel to 4.0.1. The system freezes when I shutdown or even when I switch to another console.

The logs are as follow:

kernel.log

Re: System freezes when shutdown

Since you are posting a kernel.log, are you using systemd or some other init scripts? What happens when you run "systemctl poweroff" from a terminal, without a GUI?

Re: System freezes when shutdown

I used systemd. I have tried to boot into the rescue.target and it can be powered-off normally. Below is my multi-user.target

[root@halo multi-user.target.wants]# ls -l
lrwxrwxrwx 1 root root 37 Nov  1  2012 acpid.service -> /usr/lib/systemd/system/acpid.service
lrwxrwxrwx 1 root root 38 Nov  1  2012 cronie.service -> /usr/lib/systemd/system/cronie.service
lrwxrwxrwx 1 root root 46 Nov  1  2012 NetworkManager.service -> /usr/lib/systemd/system/NetworkManager.service
lrwxrwxrwx 1 root root 36 Nov  1  2012 rc-local.service -> /etc/systemd/system/rc-local.service
lrwxrwxrwx 1 root root 40 Apr 21 08:59 remote-fs.target -> /usr/lib/systemd/system/remote-fs.target
lrwxrwxrwx 1 root root 41 Nov  1  2012 syslog-ng.service -> /usr/lib/systemd/system/syslog-ng.service
lrwxrwxrwx 1 root root 45 Nov  1  2012 vgaswitcheroo.service -> /usr/lib/systemd/system/vgaswitcheroo.service

Then I thought it's the vgaswitcheroo problem. After I delete the vgaswitcheroo.service symlink, the problem remains.

Yes, the vgaswitcheroo.service is from this package. Below is the important information after it's installed. I just followed what it said. The problem remains.

<==== INFORMATION ====>

* systemd-vgaswitcheroo-units is now installed.

* Activate it by issuing the following command as root:
*   # systemctl enable vgaswitcheroo

* In order to function properly, debugfs needs to be in your '/etc/fstab' and
* the module 'radeon' should be blacklisted in '/etc/modprobe.conf'.
* If your PC hangs on shutdown/reboot, try disabling 'vgaswitcheroo_stop.sh' by
* erasing the ExecStop-line in '/usr/lib/systemd/system/vgaswitcheroo.service'

Thanks.

Re: System freezes when shutdown

Hmm, seems related to the vgaswitcheroo package. You could try to completel yremove the vgaswitcheroo package (you can always reinstall it later) and use the open source video drivers for your video card. If that fixes your problem, you at least know what's causing it.

Re: System freezes when shutdown

Did you find the solution?
I seem to have the same problem since the new 4.0.1-1-ARCH kernel.
No swicheroo installed over here.

Still no solution. The problem remains after I remove the vgaswicheroo.

Re: System freezes when shutdown

I opened a new thread in the kernel section, as I believe this is a kernel-related problem (https://bbs.archlinux.org/viewtopic.php?id=199394).
