Suspend to RAM problem (and Suspend to Disk too)

[EugeneDudorov]

Hallo!
only started correctly work mode "suspend-to-RAM" in my notebook...
(with kernel 2.6.24.3-12)
and comes "kernel 2.6.24.3-34". Mode "suspend-to-RAM" don't working again.
What's the problems?
more precisely, not activated LCD-panel after the release of sleep.
if I turn on the console (Ctrl+Alt+1), and then (Ctrl+Alt+7)come back to
console number 7, then LCD-panel is activated.

My system:
Notebook HP Compaq 6720s ()
fedora 8
kernel-2.6.24.3-34.fc8
gnome-power-manager-2.20.0-6.fc8

Thanks.
