Suggestion: increase the VM dirty writeback time from 5.00 to 15 seconds with:

  echo 1500 > /proc/sys/vm/dirty_writeback_centisecs

This wakes the disk up less frequently for background VM activity



Suggestion: Enable the CONFIG_HPET_TIMER kernel configuration option.

Without HPET support the kernel needs to wake up every 20 milliseconds for

some housekeeping tasks.



Suggestion: Enable the CONFIG_ACPI_BATTERY kernel configuration option.

 This option is required to get power estimages from PowerTOP
