Same behavior on my VPS (KVM-based):
Output of 'uname -a':
FreeBSD archeo 9.0-RELEASE-p1 FreeBSD 9.0-RELEASE-p1 #0: Tue May 22 12:46:09 CEST 2012 root at archeo:/usr/obj/usr/src/sys/ARCHEO i386
Output of 'sysctl kern.timecounter': http://pastebin.com/GrGD5sZj
Output of 'sysctl kern.eventtimer': http://pastebin.com/Xg5zgT18
Output of 'dmesg -a': http://pastebin.com/VgLGuGD6
Setting kern.eventtimer.periodic to 1 starts the clock again. When set
to 0 and clock is stopped, machine is fully accessed via SSH, which if
you going to restart is going to hang somehow. All timer-based actions
fail of course (cron is not running any tasks, sleep(1) lasts forever,
load average does not change etc.).
