It should work fine in Linux. mp_config_ioapic_for_sci() in arch/i386/kernel/mpparse.c has an exception for Tyans: /* * Although the ACPI spec says that the SCI should be level/low * don't reprogram it unless there is an explicit MADT OVR entry * instructing us to do so -- otherwise we break Tyan boards which * have the SCI wired edge/high but no MADT OVR. */ This is for the case where there is no source override in the MADT for the interrupt defined as ACPI_FADT->sci_int. -Nate
