NSLU2 not reading real-time clock on bootup

To: port-arm%netbsd.org@localhost
Subject: NSLU2 not reading real-time clock on bootup
From: Donald T Hayford <don%donhayford.com@localhost>
Date: Tue, 03 Jun 2008 16:45:05 -0400

I built a kerrnel to add usb audio.  Source was retrieved June 2, 1800
EDT.  The startup messages on the console and an attempt to set the
clock from the command line indicate that the I2C driver isn't talking
to the clock again.

!!!!KERNEL CONFIG FILE IS:

include "arch/evbarm/conf/NSLU2"
uaudio* at uhub? port ? configuration ?
audio* at uaudio?
config netbsd-aud-npe0 root on npe0 type nfs

!!!!STARTUP MESSAGES ARE:

NetBSD 4.99.64 (NSLU2_AUDIO) #0: Mon Jun  2 08:07:31 EDT

2008
