https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=226974 --- Comment #15 from commit-hook@freebsd.org --- A commit references this bug: Author: nwhitehorn Date: Thu Apr 19 18:34:38 UTC 2018 New revision: 332788 URL: https://svnweb.freebsd.org/changeset/base/332788 Log: Fix detection of memory overlap with the kernel in the case where a memory region marked "available" by firmware is contained entirely in the kernel. This had a tendency to happen with FDTs passed by loader, though could for other reasons as well, and would result in the kernel slowly cannibalizing itself for other purposes, eventually resulting in a crash. A similar fix is needed for mmu_oea.c and should probably just be rolled at that point into some generic code in platform.c for taking a mem_region list and removing chunks.
