Since it's installed one year ago, it has 3 or 4 times unknown reason network hang (no console messages) and I have changed 3C940 to another one. The situation is still the same. The solution is just `ifconfig down up' then sk(4) goes back to work. It's our main nfs server and this problem really annoying. I look at the cvsweb, seems no major problem fix for RELENG_4 (HEAD fixs a LOR, and I suppose it's only for 5.x and HEAD). Is there any known problems? (I can't find one similar to me on -net and -stable). The recently once happened this morning, according to mrtg, it has a high network traffic (both in and out). Not sure if it is related. Here is the dmesg: skc0: <3Com 3C940 Gigabit Ethernet> port 0x2100-0x21ff mem 0xfeb78000-0xfeb7bfff irq 5 at device 9.0 on pci0 skc0: 3Com Gigabit NIC (3C2000) sk0: on skc0 sk0: Ethernet address: 00:0a:5e:19:b6:3c Any suggestion and kernel debugging I would like to try.
