I'm running 4-current (updated yesterday), but I've had this problem for a while (well over a year). I get these errors Apr 21 20:55:00 chain /kernel: de0: abnormal interrupt: transmit underflow whenever I try to transfer things to or from my network. The card is a SMC, and is probed as de0: at device 11.0 on pci0 de0: interrupting at irq 5 de0: SMC 21041 [10Mb/s] pass 1.1 de0: address 00:00:c0:f9:2f:c8 I have tried shifting the card to another PCI bus, I've tried ifconfig de0 down, ifconfig de0 up, but this doesn't solve the problem. I've pretty much tried all the suggestions that other people have suggested, except for (obviously) replacing the card. I don't think the card is dead, because it works perfectly for small files. Does anyone have any suggestions ? The problems occur whenever I transfer anything other than small files (ie greater than 100k) either to or from the client PC's to the FreeBSD machine. The collision light on the hub also goes on. Could it be the ether cable from the PC to the hub ? It's about 10-15m in length, so I haven't replaced it because that would entail ordering another length, which I haven't had time to do. netstat -i reveals Name Mtu Network Address Ipkts Ierrs Opkts Oerrs Coll de0 1500 00.00.c0.f9.2f.c8 23420 0 21720 805 826 de0 1500 freebsd-net/2 fence 23420 0 21720 805 826 after half an hour of trying to ftp install FreeBSD from the FreeBSD machine to one of the PC's. I killed it because it was averaging 2.2k/s, and it would have been faster for me to dial out and download it. The network is quite simple : (1m) ---> PC (3COM) ethernet cable - (1m) FreeBSD PC (SMC) ------------------> hub -----> PC (RealTek) (10m) - (1m) ---> PC (NE2000 clone) Any takers ?
