Hmmm… it happened on CURRENT, but once I rebuilt/reinstalled libkvm using CURRENT, it worked. Weird. So, there might be a toolchain issue going from 10.2 -> 11.0-CURRENT?

$ uname -a
FreeBSD fbsd11-i386.local 11.0-CURRENT FreeBSD 11.0-CURRENT #0: Sat Dec 19 16:34:48 PST 2015     ngie at fbsd11-i386.local:/usr/obj/usr/src/git/sys/GENERIC-NODEBUG  i386
