That will come in handy later. Thanks for the tip, but actually, I can't: ../../alpha/alpha/dec_eb164.c:92: undefined reference to `siogdbattach' ../../alpha/alpha/dec_eb164.c:113: undefined reference to `comconsole' ../../alpha/alpha/dec_eb164.c:114: undefined reference to `siocnattach' These cropped up when i added options DDB. I'll look into it, but I'll be tied up all weekend, so it will have to be next week. I have "makeoptions DEBUG=-g" in my kernel config file. That does the same job as config -g, does it not? On a somewhat unrelated note; could someone explain to me why it builds, and installs, all kernel modules? For instance, it builds and installs USB modules, even tough I don't want USB support...? It's not a major problem, I have place for them, but when rebuilding kernels like this it just wastes time. - IT
