I guess you have miss read my statement above.
The text in the square brackets says the same, suspend prepare in fact
triggers the freezing of processes.
I've just put the flow in the brackets in

hciattach takes command line arguments for the UART in use, like
hciattach /dev/tty

Stopping you right here, Because of the answer, PM_SUSPEND_PREPARE is

Hi Pavan,
Usual Linux PM would follow the below steps:
1) Freezing Tasks [enter_state() calls suspend_prepare() which calls
suspend_freeze_processes()]
2) each driver's suspend routine is then invoked (In this case wifi
driver's suspend gets called here)
3) This is followed by calling device susp

Hello All,
I have this situation in my system where the android kernel suspend

1. suspend invoked by the android
2. All user space processses get freezed including my android

I have compiled the kernel using all the required configuration for
PM.
CONFIG_PM, CONFIG_SUSPEND, CONFIG_WAKELOCK,
CONFIG_FB_EARLYSUSPEND, CPU_IDLE etc are set.
After bootup I also see the logs for request_suspend_state() being
called.
Log :
<6>request_suspend_state: wakeup (3->0) at 9253398900
if cat /sys/power/state returns a blank means your kernel do not support
suspend/on state.
I wonder do you have the kernel source, and enable the power managerment
switches in kernel config.
