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 opera-
     tion of the controller.  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 cor-
     rect 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; ini-
     tialisation 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 con-
     troller.  Initialisation 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 logical 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.
