The bug just emerged after returning from suspend mode.

After returning from suspend mode the "!" applet was on my panel alerting a kernel bug, though, as far as I have tested everything is working fine.

Hi Bao,

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. Based on your dmesg output I see PM: resume devices took 6.040 seconds. 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!
