wmake did not work so I just did a make and got the file below

So I commented out 'device  em' in the X86_64_GENERIC config file and
compiled using

#make nativekernel KERNCONF=X86_64_GENERIC

and loaded the sys/dev/netif/e1000/em/if_em.ko using kldload
and got

em0: <Intel(R) PRO/1000 Network Connection 6.9.25> port 0xdc00-0xdc1f
mem 0xfbbf6000-0xfbbf6fff,0xfbbc0000-0xfbbdffff irq 15 at device 25.0
on pci0
em0: MAC address: .......


ifconfig -a shown em0 but when I try to give it an IP Address

#ifconfig em0 inet 172.17.5.5 netmask 255.250.0.0

The system freezes and I cannot evn get the ddb prompt :-(

Thanks
