Re: [XenPPC] [PATCH] Handshake with secondary processors (take 2)

What should we do about CPUs that successfully start but take too long to ack, not sure where they'll end up.
This is prolly overkill but perhaps we shoud:

If it takes more than the proposed 5 secs, why bother -- your
system is dead anyway ;-)

Hmm.. ok.. I am being parnoid, I just don't trust the FW guys to leave a processor off line that may suck :)
How SLOF make sure the processor is good? does it?

I guess I'm looking for a way to decide that things are bad.
