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 PING 192.168.0.2 (192.168.0.2): 56 data bytes 64 bytes from 192.168.0.2: icmp_seq=0 ttl=64 time=5189.516 ms 64 bytes from 192.168.0.2: icmp_seq=1 ttl=64 time=4301.030 ms 64 bytes from 192.168.0.2: icmp_seq=2 ttl=64 time=4040.500 ms 64 bytes from 192.168.0.2: icmp_seq=3 ttl=64 time=4038.426 ms 64 bytes from 192.168.0.2: icmp_seq=4 ttl=64 time=5050.145 ms 64 bytes from 192.168.0.2: icmp_seq=5 ttl=64 time=5050.306 ms ^C --- 192.168.0.2 ping statistics --- 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? >Fix: >Release-Note: >Audit-Trail: >Unformatted:
