as reported in bug: bin/60385

this is still occurring in almost all of our systems, even those at stable, and is pretty major issue. any known progress on this? we're running ibm e325 servers.

Here's the workaround I use on a machine here that loses its stat clock after a week or so of uptime. Put this in /etc/crontab:

#  Flaky clock.  Check it every 5 minutes.
*/5     *       *       *       *       root    /usr/local/bin/fixrtc

.. and this in /usr/local/bin/fixrtc:

#! /bin/sh

# get the interrupt rate for the stat clock over one second
getticks() {
 ( vmstat -i ; sleep 1 ; vmstat -i ) |
 awk '/rtc/ { if (sum) sum+=$3; else sum-=$3 } END { print sum }'
}

ticks=$(getticks)

# It should be firing at 128 hz.  If not, kick it
if [ $ticks -lt 64 ] ; then
 echo "Stat clock has died.  Attempting to reset."
 echo
 /etc/rc.d/ntpd stop
 echo
 /usr/sbin/ntpdate -b ntp.pool.org
 echo
 /etc/rc.d/ntpd start
 echo
 echo "RTC interrupt rate is now $(getticks)"
fi




excellent, thanks much Dan. this does the trick nicely and will help a lot. hopefully there'll be a commit for the real fix for 5.4.
