140 .Ss Driver initialisation/shutdown phase
142 .It amr%d: memory window not available
143 .It amr%d: I/O window not available
145 The PCI BIOS did not allocate resources necessary for the correct operation of
147 The driver cannot attach to this controller.
148 .It amr%d: busmaster bit not set, enabling
150 The PCI BIOS did not enable busmaster DMA,
151 which is required for the correct operation of the controller.
152 The driver has enabled this bit and initialisation will proceed.
153 .It amr%d: can't allocate register window
154 .It amr%d: can't allocate interrupt
155 .It amr%d: can't set up interrupt
156 .It amr%d: can't allocate parent DMA tag
157 .It amr%d: can't allocate buffer DMA tag
158 .It amr%d: can't allocate scatter/gather DMA tag

160 .It amr%d: can't allocate mailbox tag
161 .It amr%d: can't allocate mailbox memory
163 A resource allocation error occurred while initialising the driver;
164 initialisation has failed and the driver will not attach to this controller.
165 .It amr%d: can't obtain configuration data from controller
166 .It amr%d: can't obtain product data from controller
168 The driver was unable to obtain vital configuration data from the controller.
169 Initialisation has failed and the driver will not attach to this controller.
170 .It amr%d: can't establish configuration hook
171 .It amr%d: can't scan controller for drives
173 The scan for logical drives managed by the controller failed.
174 No drives will be attached.
175 .It amr%d: device_add_child failed
176 .It amr%d: bus_generic_attach returned %d
178 Creation of the logical drive instances failed;
179 attachment of one or more logical drives may have been aborted.
180 .It amr%d: flushing cache...
182 The controller cache is being flushed prior to shutdown or detach.
184 .Ss Operational diagnostics
186 .It amr%d: I/O beyond end of unit (%u,%d > %u)
188 A partitioning error or disk corruption has caused an I/O request
189 beyond the end of the logical drive.
190 This may also occur if FlexRAID Virtual Sizing is enabled and
191 an I/O operation is attempted on a portion of the virtual drive
192 beyond the actual capacity available.
193 .It amr%d: polled command timeout
195 An initialisation command timed out.
196 The initialisation process may fail as a result.
197 .It amr%d: bad slot %d completed
199 The controller reported completion of a command that the driver did not issue.
200 This may result in data corruption,
201 and suggests a hardware or firmware problem with the system or controller.
202 .It amr%d: I/O error - %x
204 An I/O error has occurred.
