=2E..and that requires defining 'works'.

If we define it as "writes an image of some part of ram to a swap partition=
=20
that can be and does normally get restored on the next boot", then yes, we=
=20
have a working version in the existing vanilla kernel. If however you start=
=20
talking about multiple swap partitions or swap files or ordinary files, abo=
ut=20
reliability or the ability to tune it to fit your system and preferences,=20
about the responsiveness of the system post resume or the security of the=20
image (IIRC, encryption support has just been removed from swsusp), about t=
he=20
ability to get help when you run into trouble or documentation, swsusp=20
becomes less of a candidate for 'works'.

Nigel
