Wake on LAN (s2ram) via Magic Packet works only the first time after reboot

Hi Guys,

After many hours of testing the problem can described as follows:

After boot/reboot the command: "s2ram -f -a 3" works in a correct manner and puts the system into S3-State (suspend to ram). After doing a WakeUp via MagicWOL the system is awakening and the graphics works properly. Doing a second "s2ram -f -a 3" the system seems to go into S3-State but awakes within 3-5 seconds without any interaction from outside.

After a reboot the "s2ram" command works correct, but only for one time. After that, same procedure as mentioned above.

Hardware:
MB: ASROCK ALIVE NF7G-HDready with BIOS V. 2.10 (newest Version)
CPU: AMD BE-2400, 2 Cores, 2,3 GHz
RAM: 1x1 GB DDR2
HDD: Samsung 320 GB SATA in AHCI Mode
CD: DVD-ROM with IDE-Interface
NIC: Intel Pro 1000 Desktop MT (because onboard NIC doesn't work with WOL)

Software:
OS: OpenSUSE 11.0 x86 (32bit-Version) with all Updates until 28th July 2008
Drivers: Nvidia Graphics Driver installed via 1-Klick install
x11-video-nvidiaG01-173.14.09-0.1 nvidia-gfxG01-kmp-default-173.14.09_2.6.25.5_1.1-0.1 nvidia-gfxG01-kmp-pae-173.14.09_2.6.25.5_1.1-0.1

More Informations:
The used Intel Pro 1000 NIC works on a ECS AMD A780GM Motherboard correct with s2ram and WakeonLAN. So I used this NIC for testing on the ASROCK-System. On both systems the onboard NIC will not work with WakeonLan via Magic Packet.
