Release Date : Thu Nov 16 15:32:35 EST 2006 -
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
Release Date : Fri May 19 09:31:45 EST 2006 - Seokmann Ju <sju@lsil.com>
Current Version : 2.20.4.9 (scsi module), 2.20.2.6 (cmm module)
Older Version : 2.20.4.8 (scsi module), 2.20.2.6 (cmm module)
