Rajendra, I just pushed another patch to pm-20081106 for you to try. This reverts a commit[1] from linux-omap which is causing problems coming out of retention. Could you update your PM branch, and also modify the 'enabled_uarts' settings in your board-3430sdp.c file so that only the console UART is enabled. Doing this would help me understand what's working on SDP. Until I get my SDP, I'll need to rely on you for this testing.
