>From the readme:

Build 6092
----------
-Background controller cache flush routine modified
to flush smaller number of buffers during I/O without 
impacting RAID throughput. This change fixes driver 
timeout (manifesting as loss of drive access and 
filesystem errors like ext3_get_inode_loc errors) 
seen under certain Linux configurations.

Build 6089
----------
-Default changed to 30 Second Timeout for controller 
BIOS option to pause or continue when RAID 
configuration is found altered or degraded.
This behavior is same as pre v2.8 firmware behavior.

Build 6082 - Initial release of v2.8 firmware
---------------------------------------------
-The ROMB firmware modified eliminating need for 
separate SCSI driver when channel-B is configured
as SCSI. Now only one driver is needed for both 
RAID/RAID and RAID/SCSI configurations.
-Controller BIOS option added to pause or continue
after 30 seconds timeout when RAID configuration 
is found altered or degraded.
-Additional ESM fix for pulled/missing drives.
-HIM_PCI_ERR correction to power management interrupt.
-Cache flush loop decreased to prevent extensive 
spin-lock hold during high I/O.
-AFU fix to block firmware installation based on 
proper level System BIOS.
-SCSI Passthru Event filtering
-Disallow selection of drive to create raid when 
already reach maximum limit.
-Disable interrupts around doing queue accesses 
in CompleteFIB( ).
