There isn't anything CPU vendor specific within a single architecture that would affect you doing this. But I don't think that's really your question. I think you're asking if you can debug a FreeBSD/i386 kernel using a FreeBSD/amd64 system. I.e. cross-platform debugging. The answer is "no" using stock FreeBSD bits. A single GDB binary cannot be built multi-platform. -- -- David (obrien@FreeBSD.org)
