The same wifi used on one of the system I have, and I was able to reproduce the same error once a while. When this warning message occurred, the system wouldn't connect to my router, either.

I was able to workaround this by "sudo modprobe -r ath10k_pci ; sudo modprobe ath10k_pci"

I compared kernel 5.4 (used in Ubuntu 20.04) and 5.7-rc1, and there aren't fixes for this problem. The only patch that touches "__sta_info_destroy_part2" is commit b16798f5b907733 (see https://lore.kernel.org/linux-wireless/20200326155133.ccb4fb0bb356.If48f0f0504efdcf16b8921f48c6d3bb2cb763c99@changeid/)

This patch has cc'ed stable, and it will eventually be included in 5.4. A test kernel (Ubuntu-5.4.0-21.25 + b16798f5b907733) was built and is available @ https://people.canonical.com/~alexhung/LP1872351/
