Heh. I think 1) you don't realize you're saying "you don't need ntpd" to, and 2) you didn't notice the hostname of the system in some of the debugging output (ntp1.us.grundclock.com). :) 24MB physmem gone before the kernel even starts seems a little much. I wonder if some amount of that is being eaten up by a video frame buffer that maybe isn't needed on a headless system? -- Ian _______________________________________________ email@example.com mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
