+                                Sumant Patro <sumant.patro@lsi.com>
+Current Version : 2.20.5.1 (scsi module), 2.20.2.6 (cmm module)
+Older Version   : 2.20.4.9 (scsi module), 2.20.2.6 (cmm module)
+1.      Changes in Initialization to fix kdump failure.
+        Send SYNC command on loading.
+        This command clears the pending commands in the adapter
+        and re-initialize its internal RAID structure.
+        Without this change, megaraid driver either panics or fails to
+        initialize the adapter during kdump's second kernel boot
+        if there are pending commands or interrupts from other devices
+        sharing the same IRQ.
+2.      Authors email-id domain name changed from lsil.com to lsi.com.
+        Also modified the MODULE_AUTHOR to megaraidlinux@lsi.com
