Could you add a printf to the start of acpi_cpu_detach()? I want to see if we're being called before or after ACPI is stopped ("Shutting down ACPI"). Also, please do: l *AcpiGetRegister+0x61 I think it's the call to get the bus master status, which is interesting since this means that cpu_cx_count != 0 which means that acpi_cpu_detach hasn't run yet. -NateReceived on Tue Nov 18 2003 - 12:34:38 UTC
