Well, if you are able to use ddb, you can try ;-)
It should boot single user with no problems (with all cpus active), but then
will die "soon". There are varying failure modes - last time I saw curlwp
being NULL (which is impossible at this state in -current), and the kernel
crashed dereferencing that NULL pointer.
Ddb mostly works ok, but the machine (at least for me) sometimes hangs
if you go to the prom with the wrong cpu active.
Collecting various failure modes could be interesting.
