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 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 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. 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.
