I have found a way to trace from libhardware_legacy/power.c, sorry, it was simpler than what I thought, I'm using logcat through serial port. And now I can see that power.c is able to write to /sys/power/state, but again the problem is that when resuming it doesn't write "on" to "state". M On Ap

ok, I am trying to debug the libhardware_legacy.so library that contains the power.c 'C'-code module that interacts with the linux- kernel power manager, but I have this problem: I want to open the /dev/kmsg file and write to it, but I get always -1, do you know why I cannot open("/dev/kmsg", O_WR
