Thanks to everyone for the excellent help and suggestions. It looks like Steve nailed it with the suggestion to check the Known Hardware Issues FAQ. It turns out that I have an Nvidia nForce2 chipset (motherboard Asus A7N8X-VM) which has some issues with the timer interrupt. Some good debug info can be found at this link:
http://www.ussg.iu.edu/hypermail/linux/kernel/0410.1/1505.html Although my BIOS does not support the specified "Front Side Bus Spread Spectrum" option noted in that post, I did manage to fix the problem by disabling APIC via the noapic kernel option. It sync'd up within a few minutes after reboot. Here is my ntpq info after running for a couple hours: ntpq> pe remote refid st t when poll reach delay offset jitter ============================================================================== *timeclock.btbx. 129.7.1.66 2 u 121 256 377 124.382 -13.734 0.968 +server.slsware. 192.43.244.18 2 u 66 256 377 110.850 5.897 0.815 +ns0.nono.com 192.5.41.40 2 u 55 256 377 81.088 8.565 0.911 ntpq> rv assID=0 status=0644 leap_none, sync_ntp, 4 events, event_peer/strat_chg, version="ntpd [EMAIL PROTECTED] Thu May 11 09:19:35 EDT 2006 (1)"?, processor="i686", system="Linux/2.6.16-1.2133_FC5", leap=00, stratum=3, precision=-18, rootdelay=189.995, rootdispersion=69.413, peer=64196, refid=206.57.44.149, reftime=c8457d49.e26f71a7 Thu, Jun 22 2006 10:34:17.884, poll=8, clock=0xc8457dcb.560168b5, state=4, offset=-1.247, frequency=-6.417, noise=1.312, jitter=21.030, stability=30.580 I'll follow up on your suggestions for finding an NTP server in Hawai'i to see if I can improve on the delay a bit, but for now I'm stoked.
