Killer Wireless 1525 firmware crashes on suspend

[Sander Los]

Problem:
Ubuntu running on Alienware 17 R2 system hangs on suspend. The Keyboard LED's stay on and FAN keeps running. Strangely this does not happen in Fedora 29 (Kernel 4.18 & same board firmware)

System:
Ubuntu 19.04
Kernel 5.0.0-13-generic
Wireless chipset Killer Wireless 1525 (Atheros QCA6174, hw2.1)
Wireless info:
       description: Wireless interface
       product: QCA6174 802.11ac Wireless Network Adapter
       vendor: Qualcomm Atheros
       physical id: 0
       bus info: pci@0000:03:00.0
       logical name: wlp3s0
       version: 20
       serial: 40:b8:9a:ca:2b:99
       width: 64 bits
       clock: 33MHz
       capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless
       configuration: broadcast=yes driver=ath10k_pci driverversion=5.0.0-13-generic firmware=SW_RM.1.1.1-00157-QCARMSWPZ-1 ip=192.168.55.161 latency=0 link=yes multicast=yes wireless=IEEE 802.11
       resources: irq:32 memory:f6800000-f69fffff

My attempts:
1. Tried other kernels:
5.0.12, 4.20.17, 4.19.7, 4.18.16, 4.18.0, 4.16.0, 4.14.114

2. Tried several distro's based on ubuntu -> all have the same issue

3. Checked firmware from Fedora 29 (md5sum was equal) and updated firmware (not available, using latest)

4. Created systemd scripts for disabling & enabling the driver, this causes the same crashes in /var/log/syslog
See: https://forum.manjaro.org/t/solved-qca6174-freez-after-suspend/66232/11

5. Physically replaced Killer 1525 with Intel 8260 --> problem is gone, standby works perfectly

Of course i want to be able to use the 1525, so please help me solve the issue.
Happy to perform additional debugging if required.

Some additional information: It looks like NetworkManager is part of the problem / solution.
--> Linked to networkmanager <--
If wifi is disabled (nmcli radio wifi off) the suspend works as expected.
Unfortunately, when scripting this into a systemctl script hooking to suspend.target, networkmanager is killed before the script is executed, thus networkmanager cannot respond anymore to the command.

Example of this systemctl script included here:

[Unit]
Description=Network suspend service
Before=sleep.target
StopWhenUnneeded=yes

[Service]
User=root
Type=oneshot
RemainAfterExit=yes
ExecStart=/usr/bin/sudo -u $USER /bin/bash -lc 'nmcli radio wifi off'
ExecStart=/usr/bin/sleep 5

[Install]
WantedBy=sleep.target

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1827879

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

[Kai-Heng Feng (kaihengfeng)]

Does the issue still happen?

[Sander Los (sander-6)]

Yes, nothing changed as far as i know, so the issue remains

[Kai-Heng Feng (kaihengfeng)]

Please run `sudo modprobe -r btusb` before suspend and see if it helps.
