Bug#354254: hibernate: Suspend to disk doesn't work: cannot find swap device

Package: hibernate
Version: 1.12-1
Severity: normal
X-Debbugs-CC: pavel@suse.cz, linux-pm@osdl.org

Suspend to disk does not work for me with the following dmesg message:

PM: writing image.
swsusp: cannot find swap device, try swapon -a.

Yes, my swap was turned on and I checked it again. I HAVE run swapon -a.
$ swapon -s
Filename                                Type            Size    Used   
Priority
/dev/hda2                               partition       254008  0       -1

I run 2.6.15.4 kernel (not from Debian distribution).

Here is my approximate digits of memory usage during testing:

$free
             total       used       free     shared    buffers     cached
Mem:        248264      17088     231176          0       1528       9068
-/+ buffers/cache:       6492     241772
Swap:       254008         48     253960

I deem that there are enough swap space to save all my memory except
of free memory.

I have also checked that there are no "swapoff" string in files of hibernate
package except of /etc/init.d/hibernate (which runs only on boot, not on
suspend).

Attached are my kernel configuration and hibernate configuration.

I think you haven't used the "resume=<your_swap_partition>" kernel command
line argument, which is mandatory for suspend with this kernel.

I have used resume=/dev/swap

/dev/swap is a symlink to /dev/hda2

I don't think the code that uses this argument is capable of following
symlinks.  Please use resume=/dev/hda2 and see if that helps.
