**Short description of error**
When doing a very specific thing in Shader editor using Eevee rendered, my system froze. I've rebooted and tried again. It froze again, only this time when I rebooted it I was greeted by an emergency shell. My root Btrfs filesystem is unabootable. I'm currently performing disk imaging, and will attempt to fix the FS or restore the system from backup.
Here's the screen that I saw after rebooting my laptop after the second lock-up:

**Exact steps for others to reproduce the error**
I have a specific .blend file that when loaded on Manjaro Linux will freeze the system. I've tried again booting a fresh Manjaro 20.1.1. However it's a confidential client project and I cannot share it publicly.
I wasn't able to reproduce the problem on Windows 10 running on the same laptop.
I suspect the problem could be in an AMD GPU driver - it's the only thing that I believe has enough system access to mess up a roo t filesystem that was involved. And it's clear the problem was triggered by a certain material in Blender, while rendering with Eevee.
Note that the system won't freeze until I turn on Rendered view. Using Material Preview is fine.
Two first time when it happened it was immediately after I have added a mix node to add another texture to an existing image path in an Eevee material.
I thought that maybe texture sizes could be the problem, as I've been using 3 8K textures, and maybe the laptop's GPU can't handle that, but filesystem corruption should never be the result of that.
