     o	 MegaRAID Series 418
     o	 MegaRAID Enterprise 1200 (Series 428)
     o	 MegaRAID Enterprise 1300 (Series 434)
     o	 MegaRAID Enterprise 1400 (Series 438)
     o	 MegaRAID Enterprise 1500 (Series 467)
     o	 MegaRAID Enterprise 1600 (Series 471)
     o	 MegaRAID Elite 1500 (Series 467)
     o	 MegaRAID Elite 1600 (Series 493)
     o	 MegaRAID Express 100 (Series 466WS)
     o	 MegaRAID Express 200 (Series 466)
     o	 MegaRAID Express 300 (Series 490)
     o	 LSI MegaRAID SCSI 320-0X, 320-2X, 320-4X
     o	 LSI MegaRAID SCSI 320-1E, 320-2E
     o	 LSI MegaRAID SATA 300-6x, 300-8x

DIAGNOSTICS
   Driver initialisation/shutdown phase
     amr%d: memory window not available
     amr%d: I/O window not available

     The PCI BIOS did not allocate resources necessary for the correct operation of the con-
     troller.  The driver cannot attach to this controller.

     amr%d: busmaster bit not set, enabling

     The PCI BIOS did not enable busmaster DMA, which is required for the correct operation of
     the controller.  The driver has enabled this bit and initialisation will proceed.

     amr%d: can't allocate register window
     amr%d: can't allocate interrupt
     amr%d: can't set up interrupt
     amr%d: can't allocate parent DMA tag
     amr%d: can't allocate buffer DMA tag
     amr%d: can't allocate scatter/gather DMA tag
     amr%d: can't allocate s/g table
     amr%d: can't allocate mailbox tag
     amr%d: can't allocate mailbox memory

     A resource allocation error occurred while initialising the driver; initialisation has
     failed and the driver will not attach to this controller.

     amr%d: can't obtain configuration data from controller
     amr%d: can't obtain product data from controller

     The driver was unable to obtain vital configuration data from the controller.  Initialisa-
     tion has failed and the driver will not attach to this controller.

     amr%d: can't establish configuration hook
     amr%d: can't scan controller for drives

     The scan for logical drives managed by the controller failed.  No drives will be attached.

     amr%d: device_add_child failed
     amr%d: bus_generic_attach returned %d

     Creation of the logical drive instances failed; attachment of one or more logical drives may
     have been aborted.

     amr%d: flushing cache...

     The controller cache is being flushed prior to shutdown or detach.

   Operational diagnostics
     amr%d: I/O beyond end of unit (%u,%d > %u)

     A partitioning error or disk corruption has caused an I/O request beyond the end of the log-
     ical drive.  This may also occur if FlexRAID Virtual Sizing is enabled and an I/O operation
     is attempted on a portion of the virtual drive beyond the actual capacity available.

     amr%d: polled command timeout

     An initialisation command timed out.  The initialisation process may fail as a result.

     amr%d: bad slot %d completed

     The controller reported completion of a command that the driver did not issue.  This may
     result in data corruption, and suggests a hardware or firmware problem with the system or
     controller.

     amr%d: I/O error - %x

     An I/O error has occurred.
