- If you have built SCSI as modules, enabling this option can
- be a problem as the devices may not have been found by the
- time your system expects them to have been. You can load the
- scsi_wait_scan module to ensure that all scans have completed.
- If you build your SCSI drivers into the kernel, then everything

You can override this choice by specifying "scsi_mod.scan=sync"
