From my notes I've been taking:

• AMDGPU on linux with this board has a rare issue where things slow down to about 1 FPS and a bunch of lines about [drm:dc_dmub_srv_cmd_run_list [amdgpu]] *ERROR* Error queueing DMUB command: status=2 show up in dmesg. The only way to get past it is to reboot. I've had this happen maybe 3 times in the past two weeks of ownership.
• Plugging or unplugging the power while the machine is sleeping wakes it up. This is because the embedded controller for some reason sends a keystroke when this happens. You can add custom udev rules to work around this very successfully at the cost of your keyboard not being able to wake (use the power button or lift the lid instead), but it's a thing.
• Ethernet module was a disappointment because of how far it sticks out of the laptop.

On the more nitpicky side:

• Bezel is for the most part just held on magnetically. You can peel it off without any serious intention of disassembly.
• Screen resolution is an awkward size for HiDPI scaling. Some people get around this by scaling font size only, which looks fine. I've gone the wayland fractional scaling route which is a little bit of a journey.

I really like this laptop though and prefer it to my ThinkPad X1 Carbon.
