What happens when you use the latest version of s2disk?

Hello,
I'm running Arch Linux

pm-utils 1.4.0-1 (which is the latest stable release according to 
http://pm-utils.freedesktop.org/wiki/)

s2disk -V
s2disk (suspend) 0.8

uswsusp 0.8-6 (which is the latest stable release according to
http://suspend.sourceforge.net/)

Hi, Sergey
    Will you please try the latest linux master tree and see whether the issue still exists?

    If it exists, will you please try the attached debug patch and see whether it is helpful?

Thanks.

Hello,
Can't reproduce with 2.6.36-rc4. Seems to be fixed.

Thanks for confirming that...

2.6.36-rc2-git3 worked
2.6.36-rc2-git4 failed
2.6.36-rc4 works

since this doesn't appear in any actual release,
i'll assume some other issue in the early rc2 caused
it and it is now gone.  Please re-open if you see this again.
