apply this ! https://github.com/greearb/ath10k-ct/blob/master/patches/0100-mac80211-fix-txq-queue-related-crashes.patch to your kernel

[atzlinux]

Thanks for your feedback.

I don't use this NIC now, so I can't to test it.

You may close this issue.

I think the problem is that my driver will not work properly in un-patched upstream kernel. You can clone one of the kernels from my site in that case, or dig up whatever patch in my kernel fixes that assert.
