Actually on closer inspection I'd say that acpi_ns_get_device_callback is stack gunk and it isn't involved here. It isn't clear (to me) where in this mess we disabled interrupts around the set_cpus_allowed(). Chris, if this is repeatable it would be helpful to set CONFIG_FRAME_POINTER=y which hopefully will get us a cleaner trace, thanks. - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
