Random guess: is it related to CONFIG_KEXEC?

Yup, backing out kexec fixes it.

Ok. Thinking it through the differences is that I have machine_power_off
call stop_apics (which is roughly equivalent to the old smp_send_stop).
In the kexec patch that does 2 things.
1) It shuts down the secondary cpus, and returns the bootstrap cpu to
virtual wire mode.
2) It calls set_cpus_allowed to force the reboot to be on the primary
cpu.
After returning from machine_power_off. We run into a problem
in flush_tlb_mm. Because we have a cpu disabled, that is still part
of the mm's vm mask.
Does anyone know why machine_halt, and machine_power_off return?
If not I am just going to disable the return path.

Mmmm. Not sure NUMA-Q will like disconnect_bsp_APIC() much, but I guess
that's my problem, not yours ;-) I can't do init 6 at the moment, so I'm
walking on thin ice as is ... if I have to fix a couple of things up for
NUMA-Q, that's no problem.

OK ... I presume that's just because you shut down the secondaries then.
If so ... shouldn't it remove them from the relevant vm mask when it
offlines them? (probably not your code, but still)
> Does anyone know why machine_halt, and machine_power_off return?
Nope, thats ... odd ;-)

Ah ok. This could explain some of your problems with kexec if you
can't even reboot the box....

Right. The code is more about shutting down the secondaries then off
lining them. In a general purpose scenario I expect more would need
to happen.

That is what I thought.
I have sent the fixed patches to Andrew and CC'd the list so we will
see what develops.

Well, yes ... but I'm not trying to use kexec, just doing an init 0 ;-)
That worked fine before. Perhaps you want to take this code out of the
power down path, and just have it in the reboot path? Seems odd to change
the power down path if you don't need to.

Thanks, will try them sometime soon-ish ;-)

Fundamental rule of software reliability/simplicity. Build one basket
and put all of your eggs in it.
I guess I can't possibly imagine why after a system halt anyone
would want random cpus scurrying around. So this forces the issues
up to the from so they can be examined and fixed.
If the code is wrong from NUMA-Q I would like to get a correct version.

Just a last thought with my updated patch init 0 will continue to work
because it does not return machine_halt now.
Unless there was some magic I am missing.
