    ok, to make sure i understand this right: it is not safe to switch any
    local APIC in the system into clustered APIC mode on the E850x chipset
    /at all/, because if one of the CPUs gets an INIT/startup IPI message
    its local APIC will default to logical flat mode and might confuse the

    on large systems that have their APIC IDs set up to group CPUs amongst
    different clusters and hence triggered cluster mode, the chipset does
    not get confused by this, correct?
