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.

Kevin
