Investigating Hibernation Failure [SOLVED]

Hi

What can i do to figure out whats the problem with hibernation on my PC ?
When i run pm-hibernate screen goes black and then turns back to desktop . pm-suspend works flawlessly
The /var/log/pm-suspend.log is not informative as it just reports running hooks and they always report success . I really need this feature on my laptop , please get some directions
And please don't suggest using tuxonice as i have to compile a new kernel .

Any help is appreciated

Wow hibernation is now working !
To those who want to use pm-utils for hibernation :

1- you have to uninstall uswsusp and suspend2 as they interfere with pm-action
2- you have to pass the location of resume file to the kernel like this :  resume=/dev/sda4 ( where /dev/sda4 is your swap partition )
3- try blacklisting your newly added modules in MODULES array in /etc/rc.conf to see if they are causing problem
4- check /var/log/pm-suspend.log sometimes it tells something useful

cheers

For the sake of clarity - hadi's advice above implements suspend/hibernate using pm-utils with the kernel's native sleep functionality. pm-utils can also use either uswsusp or tuxonice, if required.
