Hi Sriram, From the log, the system doesn’t enter
suspend state actually, namely, during the suspend process, it encounters some
errors, which make your system execute resume operations, in your case, Maybe iva2_pwrdm and core_pwrdm
drivers reject to “sleep”, also adding “no_console_suspend” option in bootargs may
make the console print more message. To check whether your drivers are
implemented properly for PM, you can try following commands in order: Prepare the testing to your drivers: Echo core > /sys/power/pm_test Enter the testing: Echo mem > /sys/power/state Terminate the testing: Echo on > /sys/power/state This will test the freezing of processer,
suspending of devices, platform global control methods The disabling of nonboot CPUs and
suspending of platform/system devices. For more details, please refer to: http://lxr.linux.no/#linux+v2.6.31/Documentation/power/basic-pm-debugging.txt BRs Edwin 发件人: linux-pm-bounces@xxxxxxxxxxxxxxxxxxxxxxxxxx
