Thanks, good to know. On what platform is this, can you share more
details? Is it the new Dell XPS 13 9310 or something else?

This commit should fix that:

https://git.kernel.org/pub/scm/linux/kernel/git/kvalo/ath.git/commit/?h=ath11k-qca6390-bringup&id=fa4eea695afb286ae38beb30dabf251335cb4a62

I recommend using ath11k-qca6390-bringup branch, it has quite a few
fixes:

You mean that the reboot stalls and you need to turn off the laptop
using power button?
