Ben --

OK.  I ran it twice, as shown below, on my new Dell OptiPlex GX620
Mini-Tower: Intel Pentium 4 Processor 650 with HT (3.4GHz, 2M, 800MHz
FSB).  I'm running Dapper 2.6.15-26-386 #1 PREEMPT Thu Aug 3 02:52:00 UTC 2006 
i686 GNU/Linux

As far as I can tell, the new information that -D reveals is that it
gave the same number of seconds since 1969 both times, even though it
says it '...got clock tick' after it says that the select() timed out.

[EMAIL PROTECTED]:~# hwclock -D
hwclock from util-linux-2.12r
Using /dev/rtc interface to clock.
Last drift adjustment done at 1121000000 seconds after 1969

Assuming hardware clock is kept in UTC time.

I ran the above tests after I pulled the battery out of the motherboard,
waited a few hours, put it back in, and reset all the BIOS options and
rtc, just in case there was some sort of corruption there, as noted
in other bug reports.  It didn't make any difference.

I'm glad you're upgrading the status of this bug to critical.  I agree
that it's pretty serious.  I can't keep the machine's rtc synchronized
with real time, which ultimately will make a variety of messes
(e.g. CVS).
