I last built head at r223421; I upgraded sources to r223471. "make buildworld" was uneventful; building the kernel demonstrated that I needed the patch from r223474, which I applied (after which building the kernel was also uneventful). Here's a cut/paste from serial console of my build machine (laptop also failed similarly, but serial console is a bot more awkward, and the symptoms look the same anyhow): GDB: no debug ports present KDB: debugger backends: ddb KDB: current backend: ddb Copyright (c) 1992-2011 The FreeBSD Project.
