I have been using rc6 kernel 5.10, plus I git cloned the ath11k-firmware repo, and linking /lib/firmware/ath11k/QCA6390/hw2.0 -> /lib/ath11k-firmware/QCA6390/hw2.0/1.0.1/WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1/

uname -a:   Linux minty 5.10.0-051000rc6-generic #202011291930 SMP Mon Nov 30 00:36:46 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

I have had pretty good results with the wifi, except that after sleep resume, i always have to do   sudo modprobe -r -f ath11k_pci && sudo modprobe ath11k_pci   -- which takes 2 to 3 minutes (last run - 2:34).  Otherwise wifi is not working at all.

Additionally, on occasion I have observed full system lock ups that require hard reboot (long press on power button). I do not know if this is related.
