--- Comment #28 from nmr nnmmrr88+fd@gmail.com --- I get that it's triggered by Mesa, but don't you think it's a bug itself that user-space can hang the kernel? I can't even switch virtual consoles when it hangs.
I'm currently running Linux waldorf 4.19.0-2-amd64 #1 SMP Debian 4.19.16-1 (2019-01-17) x86_64 GNU/Linux
I'll report back when I upgrade to 4.20
