Subject: Ocotea board: ntpd complains that the frequency error exceeds the tolerance


Lifted from http://bugzilla.kernel.org/show_bug.cgi?id=8182

Steps to reproduce:
- Boot an Ocotea board with the mainline 2.6.20.1 kernel.
- Create an /etc/ntp.conf file with at least one NTP server and iburst mode set.
- Issue the command "ntpd -g".
- Wait about two minutes.
- Verify ntpd's status via "ntpq -pn" and by looking in /var/log/ntp.

  I asked Stefan & Josh to look at this and Stefan believes its a  
33.33Mhz clock.  So should this really be 33330000?

I have measured the clock frequency on the two Ocotea boards I have on
my desk, and both have a clock crystal of 33.3 MHz, not 33.33 MHz.
What I don't know is whether the same clock crystal is mounted on all
Ocotea boards.

Bart Van Assche.

Hmmm. From what I could read from the schematics, it should be 33.33MHz. But 
here is always a gray zone. I'll ask AMCC, what is equipped right now.

Thanks.
