[SOLVED]Systemctl Suspend fails due to NetworkManager & wpa_supplicant

TL;DR: Fixed in Kernel 4.13.5 which is now in testing
Hello,

first time posting so wasn't entirely sure where to post this, but probably a newbie question.

First install of Arch was running smoothly for 6 months, but last Thursday I had severe problems with kworker hanging, NetworkManager and wpa_supplicant refusing to stop on shutdown/reboot, and suspend instantly waking. So I decided a reinstall would potentially be a good decision, and I'm getting the same problems (leads me to believe this is probably wifi driver related or wifi card). Not sure how to resolve this after trying all weekend searching to try and find a permanent solution.
I have tried using netctl/wicd to see if the problem is NetworkManager and they also refuse to stop on reboot/shutdown.

Laptop: Acer Aspire E5-575G
Kernel: 4.13.3-1
WM: i3-gaps

The issue:
I read somewhere that this can be commonplace and therefore should be ignored, but in my case it's spammed in journal -xe constantly even when not running pacman. Also the post stated that it's potentially a memory issue, but I don't see that being the case free -h

free -h:

              total        used        free      shared  buff/cache   available
Mem:           7.7G        1.4G        5.4G        234M        1.0G        5.9G
Swap:          2.0G          0B        2.0G

this is with Firefox (all the tabs) and termite open so it doesn't seem RAM is the issue SSD failure I haven't tested.

journal -xe

Suspend also freezes and instantly resumes log states that NetworkManager and wpa_supplicant are the culprit no idea where to start for fixing that.

This for whatever reason also makes it impossible to restart NetworkManager or wpa_supplicant after the failed suspend even

 systemctl restart NetworkManager/wpa_supplicant 

doesn't work and just causes them to fail and be killed by Systemd

Any assistance would be greatly appreciated no idea how to resolve these issues. Also posting dmesg on boot just in case there's an obvious wifi related error there that I don't understand. Note this isn't all of it

*EDIT on shutdown the system unmounts and stops everything, eventually, but it just hangs when it reaches shutdown and then starts spamming the kworker issue again, and eventually shuts down 5 minutes later.

Re: [SOLVED]Systemctl Suspend fails due to NetworkManager & wpa_supplicant

I am also experiencing a similar issue. I believe that this was reported here:
https://bugs.archlinux.org/task/55872
The submitter of the above bug report has a Qualcomm Atheros QCA9377 802.11ac Wireless Network Adapter (rev 31), and as do I. Do you happen to have the same one as well? (lspci shows this info)

Further evidence that this issue is caused by the wireless network adapter is that, if I disable it, the problem goes away. Of course, that leaves me with no wifi, which is a poor tradeoff. But, if you would rather connect over ethernet until this gets fixed, go for it.

As an aside, I attempted to register for Arch's bugtracker so that I could confirm this issue there, but there seems to be a bug in the registration process. Exceedingly ironic, and reminiscent of https://www.xkcd.com/1163/. If anyone who has an existing account there happens to see this, could you mention the detail about the network adapter there?

Since there seems to be a problem with NetworkManager and dhcp, try disabling those manually first, then see if the suspend works.

Yep.
lspci

03:00.0 Network controller: Qualcomm Atheros QCA9377 802.11ac Wireless Network Adapter (rev 31)

I'll try and register. Any idea when this is will be fixed or a temporary fix? It's not a system breaking bug, but it's incredibly annoying.

*Edit: registered and commented

Linux 4.13.5 includes the fix apparently just have to wait.

Good news! I just grabbed a copy of Linux 4.13.5 from the testing repo (http://mirrors.kernel.org/archlinux/tes … pkg.tar.xz) and installed it with pacman -U. The issues with kworkers timing out have vanished. However, I did start having trouble with libmutter segfaulting when I sleep. But then and again, I upgraded all of gnome this morning. Confounding variables for the win!

Re: [SOLVED]Systemctl Suspend fails due to NetworkManager & wpa_supplicant

Same. Although it's probably a bad decision to partially upgrade my system with the newer kernel.
famous last words.

Re: [SOLVED]Systemctl Suspend fails due to NetworkManager & wpa_supplicant

The kernel is the one package where it is pretty safe to partial update, since it is largely self-contained. Anything else you should at least know what to look out for, which might differ from package to package
