[5.99.41] clock skew
Hello,
I have installed NetBSD 5.99.41 on one of my SS20 (with only one RT626
processor).
NetBSD riemann 5.99.41 NetBSD 5.99.41 (GENERIC.MP) #0: Fri Dec 17

Root riemann:[/home/pkgupgrade] > uptime
10:21AM up 3 days, 15:56, 3 users, load averages: 0.00, 0.00, 0.22
System is up for more than 3 days and I see a strange clock skew. ntpd
cannot synchronize clock (I have a local ntp server on a linux/sparc
box). I have tried to write some different values in /var/db/ntp.drift
without any result.
Is it a known bug ?
Regards,
JKB
PS: ntpd output:
