Couldn't hibernate: Swap space is encrypted
Last modified: 2009-10-29 07:16:42 EDT
Description of problem:
Hibernate used to work on my machine. But now after todays yum update I get
Oct 26 02:14:26 localhost gnome-session: devkit-power-gobject-WARNING: Couldn't hibernate: Swap space is encrypted
Oct 26 02:14:26 localhost gnome-session: WARNING: Unexpected hibernate failure: Swap space is encrypted
But I am pretty sure that my swap space is _not_ encrypted:
[root@localhost ~]# cat /proc/swaps
Filename Type Size Used Priority
/dev/mapper/VolGroup00-LogVol01 partition 1966072 0 -1
[root@localhost ~]# blkid |grep swap
[root@localhost ~]# grep swap /etc/fstab
/dev/VolGroup00/LogVol01 swap swap defaults 0 0
I assume it was caused by my upgrade to DeviceKit-power-012-1.fc12.i686

- Update to 012
- Detect encrypted swap and prevent hibernate in this case.
- When we do a delayed refresh, actually do 5 x 1 second apart rather
than 1 x 3 seconds which should fix some slow battery devices.
(but other packages - such as the kernel - was updated at the same time, so I'm not 100% sure)
Version-Release number of selected component (if applicable):
Well, _is_ your swap space encrypted ?
I have not intentionally made the swap space encrypted. How can I prove that it isn't?
I assume that encrypted swap space requires /etc/crypttab to configure a dm device in /dev/mapper which should be used as swap device? I have no /etc/crypttab and as you can see I use /dev/mapper/VolGroup00-LogVol01 directly.
I don't know. It might well be that DK-power is getting it wrong and thinks your swap is encrypted, even though it is not.
I'll ask Richard to look into this when he's back

Looks like it is not an isolated incident, putting on F12Blocker just in case

Fixed in DeviceKit-power-012-2.fc12
DeviceKit-power-012-2.fc12 works for me - thanks!
