https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=229222 --- Comment #25 from commit-hook@freebsd.org --- A commit references this bug: Author: kib Date: Mon Jun 25 11:29:04 UTC 2018 New revision: 335635 URL: https://svnweb.freebsd.org/changeset/base/335635 Log: Do not leave stray qword on top of stack for interrupts and exceptions without error code. Doing so it mis-aligned the stack. Since the only consumer of the SSE instructions with the alignment requirements is AES-NI module, and since the FPU context cannot be accessed in interrupts, the only situation where the alignment matter are the compat32 syscalls, as reported in the PR.
