Even unikernel applications have an OS compiled into the application. It's necessary to initialize the hardware it's running on, including the CPU and GPU and storage.

I suppose you could build it as a UEFI module that relies on the UEFI firmware to initialize the hardware but then you get a text only interface. But then the UEFI is the OS.

But this outage was not an OS problem. It was an application bug that used invalid pointers. If it was a unikernel it still would have crashed.

I've read that it was a driver of some kind, not an application. Applications can't cause BSODs (I hope).
