Hi ,
I am facing some issues regarding serial driver and i am using 4Aj1.1 kernel (3.0.31). my observations are follows:
by default cosole is getting started in userdebug and eng builds of JB AFS. whenever console is geting started am not facing any issues WRT getting serial logs as well as my suspend and resume functionality woks fine.
In user builds console is not getting started by default in that case. that results no more logs after the Early suspend also device its getting hanged. some times dead state.
am not getting any more logs after early suspend.
I tried tracing down the problem and found whenever console is not stared omap serial entering in to dpll cascading state their its stopping the cosole there is no logs after that.
please find the logs below,

after this point am not getting any logs to debug further. even if i tried to not stop the console also i am geting some junk characters in my minicom ,. please provide me to debug the issue further also please let me know if anyone wants more information or if i am not clear .
