+Current Version : 2.20.4.8 (scsi module), 2.20.2.6 (cmm module)

+1.     Fixed a bug in megaraid_reset_handler().
+       Customer reported "Unable to handle kernel NULL pointer dereference
+       at virtual address 00000000" when system goes to reset condition
+       for some reason. It happened randomly.
+       Root Cause: in the megaraid_reset_handler(), there is possibility not
+       returning pending packets in the pend_list if there are multiple
+       pending packets.
+       Fix: Made the change in the driver so that it will return all packets
+       in the pend_list.
+
+2.     Added change request.
+       As found in the following URL, rmb() only didn't help the
+       problem. I had to increase the loop counter to 0xFFFFFF. (6 F's)
+       http://marc.theaimsgroup.com/?l=linux-scsi&m=110971060502497&w=2
+
+       I attached a patch for your reference, too.
+       Could you check and get this fix in your driver?
+
+       Best Regards,
+       Jun'ichi Nomura
