But not on my amd64 machine, unfortunately. I applied the diff to a clean
src checkout and compiled both GENERIC and GENERIC.MP. When booting the
system with either kernel, it panics and triggers the ddb. Please see
below for its output for `trace` and `ps`.

The full dmesg leading to the panic (this is with GENERIC.MP, but GENERIC
looks exactly the same):
