Comment 14 for bug 501323

BTW, it could be a bit like on my computer... when I hibernate, computer did seems to shut down, but it looks like an event wakes it up less than 1 second after, and then it does resume, and show the lock screen which is normal after a successfull resume as far as I know.

Since I have changed the package of this bug to 'linux' kernel, you will need to rerun 'apport-collect 501323' AFTER logging in after a 'failed' suspend-to-disk would give better log files.

Note that a web page describing some test you can do is at:
