Ulrich,
As far as I know, Linux has not upgraded the kernel to the current spec. The interface is not compatible with the current xntpd. Your xntpdc display is clearly broken, but I can't help you unless the kernel implementation is compatible with the current xntpd. Please confirm that the xntpdc display is something like
xntpdc> host rackety current host set to rackety.udel.edu xntpdc> kerninfo pll offset: 2 us pll frequency: -24.710 ppm maximum error: 23568 us estimated error: 16 us status: 0107 pll time constant: 2 precision: 1 us frequency tolerance: 512 ppm pps frequency: -24.135 ppm pps stability: 0.007 ppm pps jitter: 4 us calibration interval: 256 s calibration cycles: 2004 jitter exceeded: 20 stability exceeded: 4 calibration errors: 4
This machine happens to be synchronized to a GPS receiver with PPS support, but the display for non-PPS configurations looks the same, although the last several lines normally read as zeros. The "new" interface has been standard for almost two years.
