It turns out that, as do many UNIX problems, that my kernel "bug" had nothing whatsoever to do with compiling or configuring the kernel. I did everything right, I just hadn't put the executable in the appropriate place. Our configuration at M/A-COM consists of a server and three clients. The three diskless clients boot via tftpboot which loads them up with vmunix. However, they do NOT boot up with the vmunix located in the root partition, but rather are configured to boot from a common file in the public partition (I still haven't found where that is configured, but anyway...) I had done the following on the client I was testing the kernel on: mv /vmunix /vmunix.old which is just a pointer to the common file in /pub Now, I copied in the new kernel to /vmunix and rebooted. What I didn't know is that the client was still booting from /pub/vmunix since the boot process ignores the clients actual copy of vmunix. Anyway, to make a long story short, anytime I needed to look at the vmunix executable (ps, uptime, etc) I was using the offsets specified in the new kernel, but was still running the old. It just wasn't real obvious, since I didn't setup the server and client configuration to begin with. Now, before I get the hook for being long winded about a subject that has absolutely nil to do with tcp-ip... g'day... Thanks again to those who quickly jumped to my aid.
