If any swap device is on file, hibernation should be disabled. There
were reports of users ending up with a frozen system. It should be a
matter of going through the swapon -s list. Possible patch:

Hi Ago!

Do you have any references for this. Bug numbers etc? I'd like to know,
what the underlying problem is.

Thanks for the patch.

Cheers,

That patch is not correct.
Suspend with a swap file does not work with plain swsusp v1. Using
uswsusp hibernating to a swap file is correctly handled. I don't know if
tuxonice work or not with swap files.

Bye,
Emilio

ago,

could you please comment on this?
According to the tuxonice homepage, it supports suspend to a file and I
think Emilio is right, that uswsusp does too.

Do you have any references that suspend-to-file is not supported by
kernel-swsusp?

If so, could you rework the patch (based on 1.2.3 from experimental) and
 also update pm-is-supported, so apps like gnome-power-manager not even
try to suspend in such a case.
