+/*?
+ * Tag: xpram.1

+ * Parameter:
+ *   @1: number of partitions
+ * Description:
+ * The number of XPRAM partitions specified for the 'devs' module parameter
+ * or with the 'xpram.parts' kernel parameter must be an integer in the
+ * range 1 to 32. The XPRAM device driver created a maximum of 32 partitions
+ * that are probably not configured as intended.
+ * User action:
+ * If the XPRAM device driver has been compiled as a separate module,
+ * unload the module and load it again with a correct value for the
+ * 'devs' module parameter. If the XPRAM device driver has been compiled
+ * into the kernel, correct the 'xpram.parts' parameter in the kernel
+ * parameter line and restart Linux.

+ * driver has been compiled into the kernel. Your

+ * unload the xpram module and load it again with an appropriate value
+ * for the 'sizes' module parameter. If the XPRAM device driver has been
+ * compiled into the kernel, adjust the 'xpram.parts' parameter in the
+ * kernel parameter line and restart Linux. If you need more than the
+ * available expanded memory, increase the expanded memory allocation for
+ * your virtual hardware or LPAR.
