The line before is "Stopping powerd". So, I tried to kill the powerd manually. But, when I kill 547 #killing powerd , the powerd is not stopped and the laptop makes more noise. I believe this is the issue. Kindly request you help me fix this.
I used to get this too because some of my things take a good 30 seconds or so each to cleanly shutdown. I set rcshutdown_timeout="300" in /etc/rc.conf to increase the timeout to give them more chance. This has worked well for me for several years.
