https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D206370 --- Comment #1 from commit-hook@freebsd.org --- A commit references this bug: Author: kib Date: Tue Jan 19 08:04:02 UTC 2016 New revision: 294311 URL: https://svnweb.freebsd.org/changeset/base/294311 Log: Clear whole XMM register file instead of only XMM0. Also clear x87 registers. This brings amd64 on par with i386, providing consistent initial FPU state. Note that we do not clear any extended state, at least because kernel does not understand extended state structure and consequences of zero overwrite after fninit()/fpusave().
