Minecraft freezes after 15 seconds of running and crashes PC on Linux.

Put the summary of the bug you're having here

I ran Minecraft, launching as usual, after joining a server should have run like normal, 50 FPS nothing special.

I ran Minecraft, no errors in launcher, everything loaded, after joining a server, 15 seconds later it crashed, then it crashed my PC.

Also, this is an additional note, i have more than one computer with the exact same Linux as this one, and they experienced the same thing.

Steps to Reproduce:
1. Run Minecraft
2. Join a server
3. Wait 15 seconds
