The voltage is now between 3.32V and 3.44V which seems to be ok, but after
suspending it still drops to 2.44V Vmax and 1.78V Vmin (when the compass chip
starts a measurement).
Btw.: do you know if the I2C controller and all I2C devices get suspended too?
I added some code to my kernel driver for HMC5843 to disable the device on
suspend. As it seems the functions are never called. But this may be a bug in
my code since this is the first kernel driver I ever wrote.
