    Unclear.

    acpi_enter_idle_bm() assumes that it is entered with irqs enabled,
    and so it we unconditionally disables IRQs.

    Then we unconditionally re-enable them.

    The problem seems to be that right after we enable them,
    we find that they are actually disabled, perhaps as
    a side-effect of SMM.

    Is your machine a Dell, per chance?

    Please test the patches in this bug report:

    thanks,
