Is it possible (how to) debug = the > booting process? The first step is to try with known-good bits: can you boot these = machines off the 12.0 ISO or memstick images? Can you load your kernel = and modules with the loader from the ISO/memstick? Does GENERIC built = without any flags work? If any of these don=E2=80=99t work, try to be as specific as possible = when reporting problems. For example, the exact make of mainboard (kenv = output) and the BIOS version, and any relevant BIOS settings are likely = important for problems regarding the loader. If the kernel and modules = load, you can try a verbose boot to see better how far the kernel gets. I=E2=80=99d be really surprised if the CPUs themselves would cause = trouble.
