Success, followed by failure. I successfully installed OpenBSD on my Raspberry Pi Zero 2W, it booted successfully two times in a row. I was able to SSH into it after confirming it worked on the framebuffer. One reboot later and I can no longer SSH in, it just hangs, even after being booted for 30+ minutes. Frambuffer is now unresponsive. I can ping it and get a response but I can't otherwise interact with it. Not a Wi-Fi issue, as it's connected by Ethernet via a Waveshare PoE HAT.
EDIT: Scratch that, ping gets two responses then nothing.
Hmm...fuck.
