>From what I can understand it can be a firmware bug.
The AM{P,S}DU data was read from firmware (via DMA) and get hashed. When the
driver tries to assemble it in order, the address isn't in the hash.
So please try latest upstream firmware from [1], replace
/lib/firmware/ath10k/QCA6174/hw3.0/firmware-6.bin and
/lib/firmware/ath10k/QCA6174/hw3.0/board-2.bin.
If [1] doesn't work, try the latest ath10k firmware [2], and replace
/lib/firmware/ath10k/QCA6174/hw3.0/firmware-6.bin with
QCA6174/hw3.0/4.4.1.c3/firmware-6.bin_RM.4.4.1.c3-00013-QCARMSWPZ-1.
Also ath10k-firmware/QCA6174/hw3.0/board-2.bin

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.
