Hi,

i experience packet loss on my sis0 interfaces:

4501 packets transmitted, 4340 packets received, 3% packet loss
799 packets transmitted, 745 packets received, 6% packet loss

FreeBSD pc-i.nm.ruhr-uni-bochum.de 4.6-STABLE FreeBSD 4.6-STABLE #1: Fri Jun 28
11:39:57

These are two different machines. Elitegroup K7S5A Mainboard, lan on board

sis0: <SiS 900 10/100BaseTX> port 0xd400-0xd4ff mem 0xcfffd000-0xcfffdfff irq 11 at device 3.0 on pci0
sis0: Ethernet address: 00:d0:09:e2:fa:57
miibus0: <MII bus> on sis0
rlphy0: <RTL8201L 10/100 media interface> on miibus0
rlphy0:  10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto

        media: Ethernet autoselect (100baseTX <full-duplex>)

                                                     ^^^ Why?

         

On the other side of the wire we have a 3Com SuperStack 3300TN, 
but this happens with a cisco catalyst, too. The switchs' error counter does
not increase for this ports.

Doesnt happen with other machines (with 3Com NICs)
And it seems that it doesnt happen under windoze 2000, but i will check.

Any ideas?
