Please don't shield the identity of the problem card. Others need to know of your problems. An educated guess tells me it is one of... Card: SuperMicro AOC-SASLP-MV8 Marvell 88SE6480 Driver: MVSAS Card: HighPoint RocketRAID 2680/2680SGL Marvell 88SE6485 Driver: MVSAS This ASIC/driver combo is so historically horrible with Linux that I'm surprised all the owners haven't had a big bon fire party and thrown all the cards in. Or simply Ebay'd them to Windows users, where they seem to work relatively OK. Solve your problem with a 50% more $$ LSI SAS1068E based Intel 8 port PCIe x4 SAS/SATA HBA, which uses the mptsas driver: http://www.newegg.com/Product/Product.aspx?Item=N82E16816117157 It seems this is the card most users switch to after being burned by the cheap Marvell based SAS 2xSFF8087 cards. The 1068E cards and the mptsas driver are far more reliable, stable, and faster. Many OEM cards from IBM, Dell, etc, use this chip and can be had on Ebay for less than the new retail Intel card. In your situation I'd probably buy new Intel just in case. Hope this info/insight helps. -- Stan
