Hibernating doesn't work when HDD is encrypted

[Elvis]

Well, i guess the title says it all. I do think that this behaviour is ok, nevertheless the system should recognize encrypted HDD's and turn off hibernation.

Hi Elvis,

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 5.052 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!
