CONFIG_ACPI_PROCESSOR, because it allows deep sleep states with significant wakeup latencies. But back to your original issue: You mean your notebook booted fine under vanilla Linux with ACPI disabled? That would mean I-pipe relies on ACPI here without stating this anywhere. In that case /something/ needs fixing: code, config deps, or doc. Jan PS: Please take care to not drop the list from CC.
