>Description:
I recently installed 5.3-RC1 from the available ISO.  The machine in
question has a DEC 21140 network card (de0), two processors on a 440bx
motherboard, an nvidia video card, and an aureal sound card.  After
roughly two minutes of use; I started a build for cvsup-without-gui.  A
few minutes later, I noticed my download speeds dropping rapidly, till
I was downloading at a few hundred bytes/sec.  I then killed the build,
and pinged a machine on my local 100mbit lan.  Below is the ping print:

%ping 192.168.0.2

11 packets transmitted, 6 packets recieved, 45% packet loss

The above conditions are with a machine booting a stock kernel.  I have
another machine running 5.3-RC1, and it also has a DEC 21140 based
ethernet board. I have yet to experience any network slowdowns on that
machine. 
>How-To-Repeat:
SMP, 440BX chipset, DEC 21140 ethernet controller card, pray?

Is this still a problem with modern versions of FreeBSD?
