Hi

I am unable to suspend to swap nowdays, getting message 'not enough 
swapspace'.
My swap space is 1172704k in size (1GB).

nalesnik:~# fdisk -l /dev/hda

Disk /dev/hda: 40.0 GB, 40007761920 bytes
255 heads, 63 sectors/track, 4864 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/hda1               1         146     1172713+  82  Linux swap

/dev/hda3            1606        4864    26177917+  83  Linux


Here's the message I got after issuing 'echo "4" >/proc/acpi/sleep':
