network card not detected at boot

[Vu Pham]

MY worksstation Suse 10.1 x86-64 has two network cards : 
-  eth0 device: Marvell Technology Group Ltd. 88E8001 Gigabit Ethernet
Controller
and  eth1 device: nVidia Corporation CK804 Ethernet Controller (rev a3)

Both of them are configured to start automatically at boot.

Right after boot, only eth0 is detected an configured. To make eth1
works, I have to start yast to detect the network devices again, then
stop and start /etc/init.d/network.

Is it a problem with Suse or the ethernet device or my settings ?

Thanks for your advice ?
