While trying to combine voluntary-preempt-2.6.8-rc2-L2 with software suspend 2
(swsusp2) I noticed that:
a) with voluntary-preempt = 3
- writing suspend image to disk is very slow
- resume fails !
b) with voluntary-preempt = 2
- writing suspend image to disk is very slow
- resume works but very slow
c) with voluntary-preempt = 1/0
- all works as expected

It might be interesting for you to test it with suspend(1) / pm_disk (sorry,
these don't work for me). I wonder if they'll also fail.

Regards,
Carsten
