Hi Adam,

You mentioned that you integrated the NOHZ patch.

Did it influence your power consumption?

And did you have accessive occurrences of
  34.2% (185.3)   [kernel scheduler] Load balancing tick
  23.9% (129.6)   [extra timer interrupt]
in the output of powertop?

Also: Norbert mentioned to send the HDD to sleep. Does this make sense
with SSD drives?


Thanks!

Knuth
