I=20 activated the checksumming. I have hangs _again_ (I probably always had...). Here's my /etc/uswsusp.conf=A0: # -------- # /etc/uswsusp.conf(8) -- Configuration file for s2disk/s2both resume device =3D /dev/mapper/Tamino-swap_1 compress =3D y early writeout =3D y image size =3D 967540654 shutdown method =3D platform compute checksum =3D y # -------- I don't know how I can help further... I will try without "early writeout". Any help would be greatly appreciated=A0!
