[Tinyos-help] Mica2 low power

Hi all!
I have a problem with the power consumption of the mica2 nodes,
running Null program (or any simple program e.g. running a timer) show
the consumption to be minimal, some uAs, However if I include the
ActiveMessageC module, the cunsumption grows to ~4.4mA, even if I
don't turn on the radio or do anything at all (Radio turned on results
in ~16mA, loaded cpu is around 10mA). I have tracked it back to the
Boot sequence, initializing the radio and the spi, but I coudn't
pinpoint where the additional consumption comes from. Could anyone
help me what (and how) to turn off to be back at minimal consumption
again?
Thanks,
Istvan
