From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Buy Intel used so that you're not directly contributing?
Other than that or AMD, your only other option is ARM.
I've heard that newer Ryzens play nicer with Linux.
I have a Zen 2, Zen 3+ and a Zen 4 system and they all work well very with various Linux distros (Arch, Fedora) and recent kernels.
It's very likely that your bug is specific to early Ryzen CPUs/chipsets. A couple of folks on those reports mentioned their issues went away after a motherboard/BIOS upgrade. So I think you'll be fine if you went for a more recent AMD CPU+mobo.
