I don't think Ollivier is doing PPP/hardpps() yet, at least I have not given him the semi-magic code needed for it :-) I wouldn't recommend trying it either, he is bound to have a >1 msec jitter on the DCF77 waves at his place, and that is a lousy diet for hardpps(). Poul-Henning PS: I have updated my rover page, you can see the performance of my machine with the nanokernel-PLL patch, 4.92c and a UT+ Oncore on http://phk.freebsd.dk/rover.html (This isn't using hardpps() either!) -- Poul-Henning Kamp FreeBSD coreteam member phk@FreeBSD.ORG "Real hackers run -current on their laptop."
