Release Date : Mon Apr 11 12:27:22 EST 2006 - Seokmann Ju <sju@lsil.com>
Current Version : 2.20.4.8 (scsi module), 2.20.2.6 (cmm module)
Older Version : 2.20.4.7 (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
