The aic7xxx driver will automatically + vary this number based on device behavior. For devices with a + fixed maximum, the driver will eventually lock to this maximum + and display a console message indicating this value. + + Due to resource allocation issues in the Linux SCSI mid-layer, using + a high number of commands per device may result in memory allocation + failures when many devices are attached to the system.
