Have you tried booting a custom kernel with some drivers removed? I tried PXE booting an i386 machine today using pxeboot_ia32.bin from -current, worked fine. Just tried amd64 now as well, also worked. One thing I didn't try was to pxeboot a gzipped kernel, have you tried an uncompressed one? > What's the way to debug a kernel that hangs so early that you can't > printf or drop into ddb?

The simplest way to debug something is using a serial port, do you have access to the one on this machine?
