When I installed Manjaro on an AMD ryzen 3450U laptop, I found it suffered a few serious issues.
For example, dmesg shows:

when I use the touchpad, spamming these messages continuosly over and over.
Also, bluetooth doesn’t work. Then, when I choose Suspend in Xfce menu, I can’t resume. Finally, Ive noticed there’s a noticeable battery drain when the laptop is inactive.
