You are forgiven, son


Well, as I mentioned - that powertool dump has probably caught the moment when my CPU raised and started sipping on my battery. Here's another dump with a more 'subtle' behavior:

Code:
Powertop 1.13.3
status: Unknown job: pmtrackerdaemon
Sleeping for 11 seconds before sampling
Collecting data for 30 seconds
Sample interval was 00m 30s 31769us

C#      | Ratio  | Avg/dura | Frequency | Ratio
--------+--------+----------+-----------+--------+
     C0 |   3.9% |          |   600 MHz |   1.3% |
     C1 |   2.3% |    2.4ms |   550 MHz |   0.0% |
     C2 |  65.3% |   21.0ms |   500 MHz |   3.6% |
     C3 |  15.2% |  120.5ms |   250 MHz |  95.1% |
     C4 |  13.3% |  666.6ms | 

IRQ#    | Activity   | Type           | Name
--------+------------+----------------+---------------------------
     61 |        929 |           INTC | i2c_omap
     37 |        897 |           INTC | gp
     11 |        709 |           INTC | prcm
     56 |        336 |           INTC | i2c_omap
     57 |        190 |           INTC | i2c_omap
     86 |         97 |           INTC | mmc1
I wonder why i2c_omap does have so much activity.

A few guesses:
When googling I found that this has something to do with
/media/mmc*
and therefore MicroSD card.

I read that you took out your MicroSD card but did you keep it out of the device and did you try flashing it without MicroSD?

On some other place I read a connection to "LCD Backlight:" but I
am not a N900 hardware expert.

Googling I also found these threads:
