This looks like it; the /dev/mcelog character device has been deprecated. It looks like we'll have to either port the mcelog software to the kernel-trace interface or provide rasdaemon with a tool to offline bad memory. It's frustrating that 4.12 is five years old and this hole in functionality remains. I wonder why kernel devs don't consider userspace support for their features when swinging the deprecation axe.
