On some very old PowerEdge 2400 servers I have running 5-STABLE, the RTC timer occasionally stops firing, and causes the same symptoms you're seeing. Kicking it with "ntpdate -b pool.ntp.org" starts it up again. I don't see IRQ 8 in any of my "vmstat -i" outputs on newer boxes, so FreeBSD 7 might not even use the RTC anymore. Couldn't hurt to try an ntpdate -b, though (stop ntpd first)... -- Dan Nelson dnelson@allantgroup.com
