I recently bought a GMKtek K8 (zen4 AMD Ryzen 7) with AMD Radeon 780M
graphics. It's an $800 mini-pc and I got it for $640 direct from GMKtec.
I installed FreeBSD 14.1-Release.
This message appears on-screen, but not in dmesg
/etc/rc.d/bluetooth: ERROR: Unable to setup Bluetooth stack for device ubt0
I hope someone can fix this soon.
