------- Comment #6 from robin.bankh...@gmail.com 2009-01-17 07:32 -------
Some observations from using powertop with the 2.6.28 kernel. Note that
although most other activity in the console (on a TTY, no desktop loaded) is at
normal speed, including the output of verbose commands like "ps aux", powertop
and top redraw incredibly slowly (and this can only be partially be mitigated
by keyboard activity).
Under 2.6.28, the wakeups-from-idle per second are in 5-6 figures, whereas
under 2.6.26 they were ~350 at all times. The most wakeups are caused by
schedule_hrtimeout_range and PS/2 keyboard/mouse/touchpad (each with about 39%
of wakeups). PS/2 keyboard/mouse/touchpad is on the list under 2.6.26, but
lower down the list, and the other item isn't there at all. What does that item
mean?
I'm just hoping this may provide some clues to those who can interpret them,
i.e. not me. I also don't know why this remains marked as NEEDINFO but as I
said, if there is more I can provide, please just ask.
