I was just trying this morning to netboot the box with the ata drivers disabled in the kernel (I cant disable them in the BIOS) and the amr card removed, and it at least gets to the point where I need to mount / via nfs. However, trying to type in the serial console is as if the cable were bad. Half the chars dont show up and 1/3rd are wrong. Anyways, here is the trace. Let me know if there is other info OK set hint.apic.0.disabled=1 OK boot KDB: debugger backends: ddb KDB: current backend: ddb Copyright (c) 1992-2005 The FreeBSD Project.
