https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D218452 --- Comment #9 from commit-hook@freebsd.org --- A commit references this bug: Author: markj Date: Mon Dec 18 17:26:25 UTC 2017 New revision: 326935 URL: https://svnweb.freebsd.org/changeset/base/326935 Log: Avoid CPU migration in dtrace_gethrtime() on x86. dtrace_gethrtime() may be called outside of probe context, and in particular, from the DTRACEIOC_BUFSNAP handler. Disable interrupts rather than using sched_pin() to help ensure that we don't call any external functions when in probe context.
