Yes! Indeed, the system boots perfectly well if I disable both network
adapters (bge, see
posted earlier). However, I need at least one functioning network adapter...

... and this doesn't seem to work for me.
1) Why does my system hang if I enable the network adapter?
2) Why does it only hang if APIC is enabled?
Your problem might not be related, but give it a shot !
