Ok, This is the problem: 10:38:30.867306 0:40:f4:23:ac:91 0:50:bf:a4:59:71 ip 590: tuxscreen.grange > poirot.grange: icmp: ip reassembly time exceeded [tos 0xc0] A similar effect was reported in 1999 with kernel 2.3.13, also between 2 100mbps cards. It also was occurring with UDP NFS: http://www.ussg.iu.edu/hypermail/linux/net/9908.2/0039.html But there were no answers, so, I am CC-ing Sam, hoping to hear, if he's found the reason and a cure for his problem. Apart from this message I didn't find any other relevant hits with Google. Is it some physical network problem, which somehow only becomes visible under 2.6 now, with UDP (NFS) with 100mbps?
