Dear Linus,
I thought I would forward a piece of mail to you from one of the NTP
developers. Linux has fallen from grace in their eyes (which you
perhaps already know). They are actively suggesting that people who
need to use time synchronization (NTP) switch to using freebsd.
The cited problems with Linux are that the published interfaces to the
kernel (adjtimex and friends) change too frequently to be supportable.
(The recent /proc/pci discussion is tangential but worth noting.) The
slews of bug reports received by them are almost invariably about the
Linux platform; other platforms do not seem to suffer. I've been
actively testing the recent NTP implementations (ntp 4.0 series), trying
to report bugs as seen under Linux 2.0, but enthusiasm for fixing the
bugs on their end is all but nil.

Kris,
Dave would know better which tools are useful for debugging.
One problem we've had is that the Linux kernel/syscall folks have a habit of changing things in the published (kernel) algorithms and code, and then wonder why things don't work...
It's more than neither Dave nor I have any Linux boxes - we've both looked at them and have decided to not run them anymore.

What's your drift value?
Have you considered converting to FreeBSD?
