That is consistent with your memory not being placed into self refresh properly.
5 general bugs I've seen over time:
sw bug:
- ctrl sequence issue before sleep
- CKE balls not muxed correctly
- crash on unexpected wake path
chip bug:
- (3430 >= es3 requires a errata sequence to work)
board bug:
- hooking ddr-chip-CKE wrongly or a way OMAP doesn't support
like sharing between dies.
