Comment 10 for bug 329254

@BUGabundo -- the changes for that in the suspend/hibernate cycle are limited to creating and removing a single file. So are unlikely to be realted to this issue.

As for the original message. This is triggered when resuming the system too over 5 seconds from the time it started resume to when the resume is deemed complete. Although it comes with a back trace, it is mearly informational and indicative of a relativly slow resume. The kernel still carries on in the same manner. In your case it is tellng us that your resume took approximatly 8s, which isn't mad slow:

    Feb 17 01:17:00 blubug kernel: [15010.424230] PM: resume devices took 8.112 seconds

As this message is benign I will close this one off.
