Comment 77 for bug 577916

I have the exact same problem.

After hibernating, when I power on the computer, instead of resuming it boots freshly as if never hibernated.
And network is disabled.

However in my case it happens most of the time but not always.
Indeed any of the following can happen:
- hibernates and resumes succesfully, just fine, OR
- during the hibernation process a few error messages appear and it fails to hibertate, meaning it gets stuck and never turns the power off; i then have to power it off manually, and when I power it on, it boots freshly as if nothing had happened; OR
- the same but with no error messages printed on screen: just a black screen with a blinking cursor, forever; OR
- just as described in the original post: seems to hibernate OK but then does not resume.

Importance should be set to the highest possible, this can cause data loss.
