ACPI S1 problem

I wanted to have standby mode working on my desktop so I do not have to listen to the fan all the time and also have a quick start.

As I understand it I should be using S3 mode for this but cat /proc/acpi/sleep only reports support for "S0 S1 S4 S5" so I tried S1. Dose S1 turn of the hard disks and fan ?

For some reason mysql do not want to play

kernel: stopping tasks failed (1 tasks remaining)

After stopping mysql by hand I still have problem.

That device is the graphics card.
0000:01:00.0 VGA compatible controller: nVidia Corporation: Unknown device 0045 (rev a1)

I have seen that others have this working with nvidia card why dose it not work for me?

What dose the -1 error code mean?

Pavel sent a patch for this to lkml (works with swsusp), i'll attach it.

get rid of the binary only NVidia driver if you want suspend/standby now. They are working on it but this may take some time, you know.
