I think libstand is detecting bad checksums & dropping the packets your server is sending. The most logical explanation I can see is that its summing extra memory & the extra memory its summing up is 0 for Bernd and non-zero for you... Eg, 8 months ago I saw the same netboot binary work fine for one machine (UP1000) and fail to load a kernel on another (AS500). Turning off checksums allowed the kernel to load..
