02:00.0 Network controller: Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter (rev 32)
I've updated the firmware manually as a first step trying to resolve the issue per
https://www.dell.com/community/Linux-Developer-Systems/XPS-13-9370-ath10k-pci-firmware-crash/td-p/6114945
I'm not sure whether this is related to https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1730331
but it doesn't seem to have been resolved. As a side-note, seems as if linux-firmware doesn't ship the latest for the QCA6174.
