I haven't been able to boot linux on ne2k so far, it fails somewhere down the road after loading initrd+kernel - either during initrd run or about after switching to new init (still running off network ofcourse) after mounting nfs root. So when I encountered this issue I tried non-network boot and various versions of (linux) guest and qemu-kvm - and for me, ne2k always fail (stalls) after some time. And Mulyadi Santosa mentioned it's apparently a known issue due to some timer-related problem in the code. /mjt
