>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( ).
