this morning, I also tried older released 18.04.2 image[1], which have the same older kernel 4.18.0-15-generic as this ticket description.
But, still not find ath10k error message after playing youtube for 2 hours. I'll keep using that machine to see if I can reproduce this issue.
@Stephan, Could you please try upgrade system to see if this issue can be fixed? $ sudo apt-get update; sudo apt-get upgrade -y
