Lee, the last time I saw this discussion I thought it was identified that
the multiple cores (or IIRC the multiple chips in a SMP motherboard) would
only get out of sync when power management calls were made (hlt or
switching the c-state). IIRC the workaround that was posted then was to
just disable these in the kernel build.
not using 'hlt' when idling means that you spend 10s of Watts more power
on mostly idle systems.
true, but for people who need better time accruacy then the other
workaround this may be very acceptable.
1/4 KW / day for time synchronisation.
The power company would love that.
more precisely 1/4 KW Hour / day
$0.01 - $0.02/day (I had to lookup the current rates)
they probably won't notice.

There are two ways of constructing a software design. One way is to make it so simple that there are obviously no deficiencies. And the other way is to make it so complicated that there are no obvious deficiencies.
