+ * The device specification for the cio_ignore kernel parameter is
+ * syntactically incorrect or specifies an unknown device. This device is not
+ * excluded from being sensed and analyzed.
+ * User action:
+ * Correct your device specification in the kernel parameter line to have the
+ * device excluded when you next reboot Linux. You can write the correct
+ * device specification to /proc/cio_ignore to add the device to the list of
+ * devices to be excluded. This does not immediately make the device
+ * inaccessible but the device is ignored if it disappears and later reappears.

+ * Description:
+ * The device range specified for the cio_ignore kernel parameter is

+ * User action:
+ * Correct your range specification in the kernel parameter line to have the
+ * range of devices excluded when you next reboot Linux. You can write the
+ * correct range specification to /proc/cio_ignore to add the range of devices
+ * to the list of devices to be excluded. This does not immediately make the

+ * Description:

+ * console. A possible reason why the console was not found is that the console
+ * has been specified in the cio_ignore list.
+ * User action:
+ * None, if an appropriate alternative console has been found, and you want
+ * to use this alternative console. If you want to use the CCW console, ensure
+ * that is not specified in the cio_ignore list, explicitly specify the console

+ * Description:
+ * The channel measurement facility has been initialized successfully. Format
+ * 'extended' should be used for z990 and later mainframe systems. Format
+ * 'basic' is intended for earlier mainframes. Mode 'autodetected' means that
