Debian                                           March 29, 2006                                           AMR(4)

       The  amr  driver  provides  support for LSI Logic MegaRAID SCSI, ATA and SATA RAID controllers and legacy
       American Megatrends MegaRAID SCSI RAID controllers, including models  relabeled  and  sold  by  Dell  and
       Hewlett-Packard.

       LSI MegaRAID SAS controllers are supported by mfi(4) and will not work with this driver.

Driverinitialisation/shutdownphaseamr%d:memorywindownotavailableamr%d:I/Owindownotavailable

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

       amr%d:busmasterbitnotset,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'tallocateregisterwindowamr%d:can'tallocateinterruptamr%d:can'tsetupinterruptamr%d:can'tallocateparentDMAtagamr%d:can'tallocatebufferDMAtagamr%d:can'tallocatescatter/gatherDMAtagamr%d:can'tallocates/gtableamr%d:can'tallocatemailboxtagamr%d:can'tallocatemailboxmemory

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

       amr%d:can'tobtainconfigurationdatafromcontrolleramr%d:can'tobtainproductdatafromcontroller

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

       amr%d:can'testablishconfigurationhookamr%d:can'tscancontrollerfordrives

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

       amr%d:device_add_childfailedamr%d:bus_generic_attachreturned%d

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

       amr%d:flushingcache...

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

   Operationaldiagnosticsamr%d:I/Obeyondendofunit(%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:polledcommandtimeout

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

       amr%d:badslot%dcompleted

       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/Oerror-%x

       An I/O error has occurred.
