Here you go.. For what it's worth, your debugging in clocksource_adjust seems
to only pop before we start userspace, and get_realtime_clock_ts only once
userspace starts.

My speculation about the RTC module turns out to be a red herring - I tried
a kernel with it built in, and the problem still manifested and cleared itself
early in rc.sysinit.  Checking the code there, what seems to matter is that
rc.sysinit calls '/sbin/hwclock --hctosys --utc'.

Output of 'hwclock --debug':

hwclock from util-linux-2.13-pre6
Using /dev/rtc interface to clock.
Assuming hardware clock is kept in UTC time.
Waiting for clock tick...
...got clock tick
Time read from Hardware Clock: 2006/07/05 07:57:52
Hw clock time : 2006/07/05 07:57:52 = 1152086272 seconds since 1969
Calling settimeofday:
        tv.tv_sec = 1152086272, tv.tv_usec = 0
        tz.tz_minuteswest = 240

Absolutely nothing edifying there..

The dmesg, with all the suggested patches so far applied.  Looks like something
starts off uninitialized - we get the first 'big adj' squawk right after we
allocate the console - we don't allocate the tsc timesource for another 4
seconds or so.

I'll bite - what *am* I using as a timesource for those first 4 seconds? :)
