I want to get my system into suspend mode. I stopped devMode and unplugged the usb cable.
The system then goes to supsend mode and only uses ~3mA. However it goes up to ~50mA every couple of seconds and then goes back to sleep. When it wakes up I get several of these kind of messages:
[ 4651.232216] Freezing of tasks aborted after 0.006 seconds
[ 4651.283368] Freezing of tasks aborted after 0.007 seconds
[ 4651.330270] Freezing of tasks aborted after 0.005 seconds
[ 4652.018113] Freezing of tasks aborted after 0.634 seconds
Checking /sys/kernel/debug/wakeup_sources and /sys/power/wake-lock both are empty.
What could be causing this frequent wake-up and how can I disable it?
