Hi,

I'm running i386 port -current on AMD64 hardware with a nfe Ethernet
interface.  I have been experiencing Ethernet lock-ups ever since I
started using this system.  I just build a new kernel from fresh
sources, but the problem still exists.  It seems I can repeat the
problem by starting Opera with multiple windows.

The machine is still alive, but Ethernet is completely dead (no ping
response etc.).  Doing ifconfig down/up does not help.  Sometimes
nfe comes back alive after 10-15 seconds, most often it requires a reboot.

dmesg:
