Suspend to ram error
 

Hi.
I'm running gentoo kernal 2.6.22-r8 and previusly echo mem > /sys/power/state has worked fine, but now it stoped working, (maybe becouse i've change something in my kernelconfig or re emerged somthing with new flags).
Well the problem is that if i try to suspend the screen turns blank, execpt for one frame blinking in the top left corner. After this i have to do a hard shutdown and reboot.
Anyone who knows what to do?

now worries fixed it by myself but the problem still exists if i suspend to ram in a consol, then the screen turns black when i resume and i cant do anything but reboot. The consol is open and i can write in it but i dont see anything
