Author: adrian Date: Sat Mar 2 08:12:41 2013 New Revision: 247615 URL: http://svnweb.freebsd.org/changeset/base/247615 Log: Disable the ctl driver in GENERIC. It unfortunately steals a fair chunk of RAM at startup even if it's not actively used, which prevents FreeBSD VMs of 128MB from successfully booting and running.
