omap-pm: Console not suspending

Commit Message

Hi,
	I'm using the latest pm patches with android-2.6.29, and I have a new  
situation where the console tries to suspend, it tries to fade a bit,  
but then wakes up. On the console output, I see the following error  
message:

PM: Syncing filesystems ... done.
Freezing user space processes ... (elapsed 0.00 seconds) done.

Should these options be set?

# CONFIG_NO_USER_SPACE_SCREEN_ACCESS_CONTROL is not set
# CONFIG_CONSOLE_EARLYSUSPEND is not set

I have recently made some u-boot modifications to enable UART2. One of  
the changes removed GPIO_144 - LCD EN as shown below.

Will that have any effect?

iff --git a/board/omap3/overo/overo.h b/board/omap3/overo/overo.h

   MUX_VAL(CP(UART1_CTS),		(IEN  | PTU | DIS | M4)) /*GPIO_150- 
MMC3_WP*/\


Best regards,

Elvis
