I then tried downgrading the motherboard BIOS to the F3 release that I was running previously but again this made no difference. So it would seem that this is a problem is to do with a change in FreeBSD-STABLE between r225723 and r232477. I'm wondering whether this is due to the new LSI authored driver for chips such as the LSI SAS2008 that are used in the SuperMicro AOC-USAS2-L8i. I know this driver is in CURRENT but do not know if it's in 8-STABLE. Does anyone know if and when this driver was merged from current to 8-STABLE ? If I can work out what revision that occurred in I'll go back to just before then to confirm if the problem exists. Matt
