HP Smart Array P440ar lockup error, server reboot. FW 6.60

HI guys,

for two months I have this error on my servers, DL380 G9.

1. Option ROM POST Error: 1719-Slot 0 Drive Array - A controller failure event occurred prior to this power-up. (Previous lock up code = 0x12) Action: Install the latest controller firmware. If the problem persists, replace the controller.
2. 
   Option ROM POST Information: 1792-Slot 0 Drive Array - Valid Data Found in Write-Back Cache. Data will automatically be written to drive array. Action: No action required

the server freezes and then restarts, it does not show any errors in the /var/log/messages

we have already updated firmware, drivers S.O (hpsa), bios, we did not get a newer fw for the model disks (EG000300JWFUQ), for 15 servers we have 5 restart with the same error.
