Thanks to your guidance, I found out that I had a large "systematic
drift rate" in /etc/adjtime file. This must have been the reason why the
hwclock was set behind. So I've set the drift to zero (actually just
deleted the file and let the system create a new one) and I hope things
will be ok now. :-)
Are you on baselayout-1 still or -2 (which is still ~arch)? IDR the
details on baselayout-1, but at least with -2, you can set it not to use
the adjtime file at all. If you're on -2 and can't find the details
yourself, post to that effect and I'll try to find them for you from this
end.
Particularly if you're having trouble with the clock interrupt failing
(as you mentioned you are), if you sync via NTP, that file can cause more
problems than it solves, because the system keeps deciding the clock
isn't working right and setting a larger adjustment, which fights what
ntpd is already doing. Thus if you're running ntpd anyway, it's best to
disable use of that file entirely, /especially/ if as I said your acpi or
whatever is screwing it. If you're still on baselayout-1 and can't
figure out how to disable adjtime, it may be worth putting a rm in /etc/
conf.d/local (make it conditional on there actually being a file to rm,
so the rm doesn't error out if it's not there, and ensure the local
service is in your initlevels as appropriate) for both local_start and
stop, so it's regularly removed before it starts getting to be too big of
a problem.
# equery l |grep baselayout
sys-apps/baselayout-1.12.11.1
So I'm on baselayout-1.
I attach the /etc/init.d/clock which shows a local "readonly" variable
that controls a "--noadjfile" option.
What does the following test do?
if ! touch /etc/adjtime 2>/dev/null ; then
readonly="yes"
elif [[ ! -s /etc/adjtime ]] ; then
echo "0.0 0 0.0" > /etc/adjtime
