Big update, I updated my motherboard to the newest BIOS (vF4) and it has helped dramatically with the amount of errors in dmesg. But the issue with the connection dropping after some time remains. I added amd_iommu=off to my kernel parameters and ran sudo iw wlan0 set power_save off. I did NOT apply the kernel patch you included yet. I ran dmesg when my connection dropped and saw a bunch of 'failed to update XX RXBD info: -11' errors again. I managed to capture the connection drop in a recording so you can see what it looks like on my end. My connection will remain 'broken' indefinitely until I toggle airplane mode.
