One user (moparisthebest) over the IRC channel got an AMD based Framework recently (Ryzen 7840U, 64gb DDR5). Apparently, they can’t make Haiku boot on it yet (but I have no details on what they tried… beta4 vs nightlies, etc).
And I’ve seen @kallisti5 mention CPU speed issues with Intel based Frameworks on Haiku. Maybe he can chime in.
