error in kernel.log - initcall software_resume returned -2


Hi,

I have found following in kernel.log

kernel: [ 2.595644] PM: Hibernation image not present or could not be loaded.
kernel: [ 2.595647] initcall software_resume+0x0/0x30 returned -2 after 2 usecs
kernel: [ 2.595648] initcall software_resume+0x0/0x30 returned with error code -2

Could please anybody explain me what does it mean ?
where can I found some documentation about it ?

thank you,
kind regards,
M.

Literally what it says: there is no partition configured where a resume signature could be found or it couldn't be loaded. It's an info level message (not a warning).

You'll find it with comments in kernel/power/disk.c and kernel/power/hibernate.c (show here is 2.6.33):
Code:
647 /**
648  *      software_resume - Resume from a saved image.
649  *
650  *      Called as a late_initcall (so all devices are discovered and
651  *      initialized), we call swsusp to see if we have a saved image or not.
652  *      If so, we quiesce devices, the restore the saved image. We will
653  *      return above (in hibernate() ) if everything goes well.
654  *      Otherwise, we fail gracefully and return to the normally
655  *      scheduled program.
656  *
657  */
Basically a follow-up to the PM: Hibernation message. It's not an error unless you have resume configured and it's not working properly.
