+Current Version : 2.20.4.7 (scsi module), 2.20.2.6 (cmm module)
+Older Version   : 2.20.4.6 (scsi module), 2.20.2.6 (cmm module)

+1.      Sorted out PCI IDs to remove megaraid support overlaps.
+        Based on the patch from Daniel, sorted out PCI IDs along with
+        charactor node name change from 'megadev' to 'megadev_legacy' to avoid
+        conflict.
+        ---
+        Hopefully we'll be getting the build restriction zapped much sooner, 
+        but we should also be thinking about totally removing the hardware 
+        support overlap in the megaraid drivers.
+
+        This patch pencils in a date of Feb 06 for this, and performs some 
+        printk abuse in hope that existing legacy users might pick up on what's
+        going on.

+
+2.      Fixed a issue: megaraid always fails to reset handler.
+        ---
+        I found that the megaraid driver always fails to reset the
+        adapter with the following message:
+                megaraid: resetting the host...
+                megaraid mbox: reset sequence completed successfully
+                megaraid: fast sync command timed out
+                megaraid: reservation reset failed
+        when the "Cluster mode" of the adapter BIOS is enabled.
+        So, whenever the reset occurs, the adapter goes to
+        offline and just become unavailable.
