https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=233414 --- Comment #12 from Sean Bruno <sbruno@FreeBSD.org> --- (In reply to Mark Johnston from comment #10) Just so that its clear, this patch works for me on the Tyan P8 in the cluster. I can boot a MemGuard kernel and turn the knobs on/off. I'll leave it to you folks to decide if how you want to commit the fixes. ---<<BOOT>>--- Copyright (c) 1992-2018 The FreeBSD Project.
