You might have a similar problem as me, where the SMI interrupt is misconfigured as active-low instead of active-high, so it storms the system. Does disabling ACPI make a difference? Since it's SMP, does disabling APIC (and thus turning it into UP) make a difference? ScottReceived on Mon Mar 08 2004 - 23:08:18 UTC
