This has been a relatively long standing problem, John. I think its possibly related to some access path in the nforce2 chipset as it seems to plague that chipset worse than others. But its long been, and I had forgotten, that if ntpd didn't work, turning off the ACPI stuff was the fix.
It had worked for a few kernel.org kernels and I had become complacent. My mistake.
OTOH, calling it a local bug, no, I certainly wouldn't call it a local to my machine bug. Jdow OTOH, running an FC4 box, has it enabled, and hers is working just fine. She is I believe, running the FC4's latest kernel too, so maybe the redhat people have massaged it. However, at one time several months ago I believe she also had to have a grub argument turning acpi=no.
There was a bunch of ntp related patches submitted recently, and I have no idea which of them may have restored the broken acpi vs ntp scenario to its formerly broken status, again.
Should it be looked at? Certainly, but I don't have the knowledge to do so. So I build kernels, and report problems areas. The canary in the coal mine so to speak. :-)
