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.
