 You should not be using the TSC for timekeeping if you change the
 frequency of it.

So, what should be done to restore the proper behavior of the
timekeeping on these systems?

 This indicates that the problem was introduced in a kernel change between
 Aug 2 and Aug 9 and that acpi is not at fault.  Try searching the cvs-all
 archives between those dates (and perhaps narrowing the date more).

To help narrow the date:  I'm also seeing this problem on a Thinkpad
A22p with -current from ~7pm on Aug 8.  I just recently switched to
-current so did not realize this was a new issue, and was trying to
determine if I had a configuration error of some sort.

In addition, I had one weird instance where the clock did the opposite
and increased the speed by the same ratio.  I haven't been able to
reproduce this yet.  (Maybe starting the system in a lower CPU speed
setting and then stepping up would cause it.  I will test this.)

Let me know if you want me try anything or pass along configuration
information.
