/c0 Firmware Version = FE9X 4.10.00.007
The latest is:

9.5.1-9650-Upgrade.zip
9.5.2-9650-Upgrade.zip
9.5.3-9650-Upgrade.zip
9650SE_9690SA_firmware_beta_fw4.10.00.016.zip
9650SE_9690SA_firmware_beta_fw_4.10.00.019.zip <- latest

Hum well, this is beta, I'd rather stick to released firmware :) His
firmware is actually the latest stable version for the 9650.

Yes, but it specifically addresses issue with resets:


019:
 SCR FIRM03219 Pchip reset interrupt not handled
 SCR FIRM03220 Put parity segment to free state completely when deallocate 
unused parity segment

016:
SCR 2196:  Unexpected controller soft resets
Fixed an issue with regards to  deferral of write and read commands to help 
eliminate unexpected soft resets.

SCR 2217: Incomplete unit after multiple power failures when a RAID 1 unit is 
initializing after a rebuild.
This issue is fixed in this firmware version.

SCR 819: Controller may assert when cache is disabled in a RAID5/RAID6 
configuration under heavy I/O load.
This issue is fixed in this firmware version.

SCR 2214: Performance drops during SES polling.
Fixed the issue where performance drops when a Storage Enclosure Processor 
(SEP) takes up to 700-800 msec to respond to SES polling.
