Hello, I am experiencing some weird problems with the dc-driver for a specific ethernet-card ... the Compex Freedomline (10/100 Mbps). The card perfectly seems to autodetect the mode it should operate on and seems to indeed be working just fine just after the system has booted up. --[dmesg]------- dc0: <Intel 21143 10/100BaseTX> port 0xb400-0xb47f mem 0xdd000000-0xdd00007f irq 11 at device 12.0 on pci0 dc0: Ethernet address: 00:80:48:e7:1a:8e miibus0: <MII bus> on dc0 dcphy0: <Intel 21143 NWAY media interface> on miibus0 dcphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto --[ifconfig]------ sl0: flags=c010<POINTOPOINT,LINK2,MULTICAST> mtu 552 ppp0: flags=8010<POINTOPOINT,MULTICAST> mtu 1500 lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384 inet 127.0.0.1 netmask 0xff000000 dc0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 inet 130.89.226.126 netmask 0xffff0000 broadcast 130.89.255.255 ether 00:80:48:e7:1a:8e media: autoselect (100baseTX <full-duplex>) status: active supported media: autoselect 100baseTX <full-duplex> 100baseTX 10baseT/UTP <full-duplex> 10baseT/UTP 100baseTX <hw-loopback> none Downloading an 128 MB-file from the network to /dev/null results in speeds like 9.8 MB/s (close to the theoretical maximum for a 100 Mbps network) After a (little) while though network performance almost comes to a halt somewhere around 6 to 32 kB/s ... and never seems to "recover" again. --[uname]------ FreeBSD cam043216.student.utwente.nl 4.0-CURRENT FreeBSD 4.0-CURRENT #0: Sat Feb 19 10:29:30 CET 2000 dingo@cam043216.student.utwente.nl:/usr/src/sys/compile/DINGO i386 Anybody that could help me out trying to figure out why the card seems to break down like this ? -- Pascal Hofstee < daeron @ shadowmere . student . utwente . nl > Managers know it must be good because the programmers hate it so much.
