--- Comment #11 from [email protected] --- A commit references this bug: Author: kib Date: Fri Feb 12 07:27:24 UTC 2016 New revision: 295560 URL: https://svnweb.freebsd.org/changeset/base/295560 Log: If full width writes to the performance monitoring counters are supported, use full-width aliases MSRs for writes. This fixes the "[pmc,X] negative increment" assertion on the context switch when clipped counter value is sign-extended. Add definitions for the MSR IA32_PERF_CAPABILITIES needed to detect the feature.
