I put my desktop computer to sleep and resumed it later. I was able to log back in without any issue and everything appears fine. However, apport appeared and suggested I report this bug.

Hi Chris,

The warning reported here typically indicates that it took longer for your system to resume from suspend than expected. I believe there is a 5 sec barrier which your system likely exceeded. Typically you'll see something similar to "PM: resume devices took 8.664 seconds" in your dmesg output when this happens. A patch to prevent this warning has been applied via bug 464552. As a result I'm marking this as a duplicate to bug 464552. Please continue to track this issue at that report. Thanks!
