Well, for what it's worth, using a USB serial console to capture output, all you get is:

[ 814.016541] PM: Syncing filesystems ... done.
[ 814.018516] PM: Preparing system for mem sleep
[ 814.100393] Freezing user space processes ... (elapsed 0.01 se

before it goes to sleep, and it doesn't output anything on (attempted) wakeup. Though I don't know if this is due to USB being woken up quite late or something.
