Well, maybe I celebrated too soon.

After recompiling the kernel with "device igb" it shows no errors in the dmesg and I did ifconfig and igb0 and igb1 both showed up.  But, it wasn't actually usable.  I tried to ping the gateway and got this on the console:

vm_thread_new: kstack allocation failed
No more processes.

and the pings were unsuccessful.

I tried doing ifconfig igb0 down and then up again and same thing.

Ideas?  

Thanks,
Alan
