Hi,

Few hours ago I have updated my machine to latest RELENG_7.
daemon% uname -an
FreeBSD daemon.micom.mng.net 7.1-PRERELEASE FreeBSD 7.1-PRERELEASE #6: 
Tue Nov 18 02:05:57 ULAT 2008 
tsgan@daemon.micom.mng.net:/usr/obj/usr/src/sys/GDAEMON  i386
daemon%

When I try to issue command shutdown -p now, system paniced.
