Release Date : Fri Nov 11 12:27:22 EST 2005 - Seokmann Ju <sju@lsil.com>
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.
Signed-off-by: Daniel Drake <dsd@gentoo.org>
---
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.

The hotplug concept may be extended to SCSI devices. Currently, when an

HBA is added, the scsi_scan_host() function causes a scan for SCSI devices
