Yes, IIRC that was some of the models shipping with a non-Intel network card, not all were affected. Same with the Framework and its power states not working.

Unfortunately Linux "support" means little, you have to go by other people's experiences with the specific laptop or at least the specific hardware pieces used by it. But if you check before you buy, which is a pretty trivial affair for anyone tech-savvy enough to manage their own Linux install, or if you're careless and lucky, things go swimmingly.
