I am also having this issue. 100% of the time, if the SD card is mounted, then the system will lock when put to sleep. Best I can tell, it is trying to put the SD card to sleep, and cannot due to it being mounted. Unmounting the SD card by hand just prior to sleeping the system works, also 100%. However, while that is a good short-term solution, is it not a lasting one. If there is anything anyone needs done to show this issue in addition to what is mentioned, and the logs shown earlier, just ask.
Also, if it helps, I checked several logs, with no discernible difference in the logs between a successful suspend, and an unsuccessful one, Right up to before the statement that the CPU is being put into a sleep mode. (I don't remember the exact wording right now). When comparing them, there was that statement, then the one that it is waking.
Anything else I can contribute to assist in this effort, please let me know.
