Worked out on the wakelock issue, so now cat /sys/power/state does not show any module holding a wakelock Also, I was able to put off the LCD by executing: echo 1 > /sys/devices/platform/s3c-fb/graphics/fb0/blank
Anyways, I was hpoing after inactivity for sufficient time the userspace process should freeze and suspend routing must get invoked. Still stuck on getting the suspend sequence working after this :( Regards, Sunil On Sep 16, 10:57 am, Sunil Pillai <sunilpillai....@gmail.com> wrote: > I tried cat /sys/power/state & it outputs > radio-interface. > > Assuming that the RIL is basically holding a wakelock i tired > debugging using- > echo 15 > /sys/module/wakelock/parameters/debug hoping it to print all > wakelock acuire & release sequences. > This didn't print anything :( > > I hope I'm on track unless has a useful comment at this point! > > Regards, > Sunil > > On Sep 16, 12:31 am, Sunil Pillai <sunilpillai....@gmail.com> wrote: > > > > > > > > > Hello All, > > > I am using android 2.6.35 kernel with a platform using s3c2410 > > processor.
