This kind of failure is common. Don't blame the windowserons. It's not a platform-specific failure as I've read elsewhere and people believe it because it first appeared on the debian mailing lists. It's a hardware bug that affects all systems. But to reproduce the failure, you need to get a compiled code that is very difficult to obtain, which is to have a very small loop (less than 64 microinstructions). What the sky/kabylake does is to infinitely parallelize this code, saturating the CPU resources.
