hibernation for android in Cortex A8
Im working on a freescale imx53 board with android 2.3 running on it. I'm trying add hibernation support for it. The kernel version im using is, 2.6.35, which doesn't have hibernation support for Cortex A8 series. So I used the patch form this link
for adding hibernation support for Cortex A8, and it worked well except while resuming from hibernation i see the following log and the system is in a freezed state, even the console and other devices are completely freezed, so its difficult for debugging with out console being enabled,
I think Im missing some steps wile resuming from hibernation , please post your suggestions.
The log while resuming is ,
Freezing user space processes ... (elapsed 0.00 seconds) done.
Freezing remaining freezable tasks ... (elapsed 0.01 seconds) done.
