What is the firmware on your LSI2008 controllers?

I am having weird situation with one server that has LSI2008, on 
9-stable and all SSD configuration. One or two of the drives would drop 
off the bus for no reason sometimes few times a day and because the 
current driver ignores bus reset, someone has to physically remove and 
re-insert the drives for them to come back. Real pain.
My firmware version is 12.00.00.00 -- perhaps it is buggy?
