In the presence of interrupt-remapping, we need to change the interrupt-remapping configuration aswell as modifying IO-APIC for virtual wire B mode. To keep things simple during the crash, use virtual wire A mode (for which we don't need to touch io-apic and interrupt-remapping tables). Signed-off-by: Suresh Siddha Cc: Eric W.
