Public bug reported:
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.
