Hi,
i have a few more kernel related questions. If i want to have low current in 
susped (25mA) i have to rfkill bluetooth wifi and gps first. Is this how it is 
supposed to work or should this be done by kernel? Without rfkilling i have 
current ~200mA.

And one more thing, sometimes the kernel suspends and the immediately resumes 
again. Dmesg shows this:

[ 1470.015624] Freezing user space processes ... (elapsed 0.01 seconds) done.
[ 1470.036987] Freezing remaining freezable tasks ... (elapsed 0.02 seconds) 
done.

[ 1471.591735] PM: resume of devices complete after 1049.438 msecs
[ 1471.637786] Restarting tasks ... done.
[ 1491.989135] PM: Syncing filesystems ... done.

Any idea what is waking it up? Unfortunately it's not easily reproducible... 
Reboot fixes it.
