Hi, I have a system running -CURRENT that in top(1) is showing ~20% CPU usage for the system at all times. Any ideas what could be causing this, or how I would go about diagnosing this further? Nothing in the logs. Thanks, Lars PS: dmesg attached, in case it helps: Copyright (c) 1992-2013 The FreeBSD Project.
