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? Daniel
