https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D237968 --- Comment #1 from commit-hook@freebsd.org --- A commit references this bug: Author: kib Date: Tue May 21 22:56:22 UTC 2019 New revision: 348075 URL: https://svnweb.freebsd.org/changeset/base/348075 Log: Do not call hw_mds_recalculate() from initializecpu(). If MDS mitigation is enabled by the tunable but MDS microcode is not early-loaded, software mitigation is selected. This causes initializecpu() to try to allocate memory which makes boot process very unhappy. Create SYSINIT that runs sufficiently late to succeed.
