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. ** Affects: ubuntu Importance: Undecided Status: New ** Tags: 1525 hangs killer qca6174 suspend -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1827879 Title: Killer Wireless 1525 firmware crashes on suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1827879/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
