Thinkpad X200 reboots on shutdown

Hi,

when I try to shutdown my Thinkpad X200, instead of powering off, it simply reboots. I searched the forums for a while and found this:

https://bbs.archlinux.org/viewtopic.php?id=138318

Anyways, this thread seems to be pretty old, and I thought that since the switch over to systemd, the rc.shutdown scripts int /etc wouldn't be run. I tried to remove the e1000e, ehci_pci and ehci_hcd manually before shutdown, but that didn't help either.

The problem is obviously related to some power saving means, because it only happens when the laptop is running on battery. I use tlp for power saving. I tried so set

USB_AUTOSUSPEND_DISABLE_ON_SHUTDOWN=1

in /etc/default/tlp, but didn't help either.

I don't know if it makes any difference, but I always shutdown my laptop with

systemctl poweroff

So does anyone still have this problem too? All I can find on the internet seems to be from over a year and not using systemd. Any help into the right direction would be very much appreciated

Re: Thinkpad X200 reboots on shutdown

I did some further research and it seems as if the issue might be related to a bug in the mei kernel module.

When I do

# rmmod mei_me
# rmmod mei 

before shutdown, everything works.

So the whole thing might be related to this bug:
https://bugs.archlinux.org/task/36288

I'm not sure, what exactly the mei_me and mei modules exactly do, so I'll probably just blacklist them, until this gets fixed.
