Hi All! We have several machines running SuSE 8.0 and I am really concerned about these messages, as they suddenly appeared on four different machines. The messages file is filling up with messages like: Oct 22 15:10:08 co-app-11 kernel: icmp v4 hw csum failure Oct 22 15:10:48 co-app-11 last message repeated 2 times The references in Goolge that I found indicate that this is a problem is the e100 driver, which we have. The solution is to set the module parameter to XsumRX=0 to turn off the checksumming. The thing that is really bothering me is why this started all of a sudden on multiple machines. In one case the machine has an uptime of 168 days and then 467 days in another case, so I don't see it as a problem caused by rebooting. Could it be that there is some other machine on the network causing these problems? If so, how? Any help is greatly appreaciated. Regards, Jim Mohr
