I'm trying to debug a possibly failing CPU, so I thought it would
be easy just disable the cores using machdep.hlt_cpus and see if
we see the panic's we've been seeing.
The problem is it seems ULE doesnt properly support machdep.hlt_cpus
and still schedules processes onto the halted cpus which obviously
causes problems.
Can anyone confirm this behaviour? Should machdep.hlt_cpus and I assume
the logical counterpart never be used with ULE?
Regards
Steve
