However, you should definitely define the SMP_DEBUG option if you haven't already. I've been building kernels for a while now with the following additional pertinent options: options INVARIANTS options INVARIANT_SUPPORT options DIAGNOSTIC options SMP_DEBUG options WITNESS As for not being able to get a crash dump, I've been using ddb/gdb, so I'm not of much help there.
