We can only reproduce this problem at a specific site which we no longer have access to. At that site, we had problems with both HP OEM'd Maxtor and Fujitsu drives. I also don't have any other u320 cards to try this on other than Fusion. Eric? Have you been able to reproduce this problem on Linux at LSI? > > If it's something drive specific, we probably need more of a blacklist > in the spi transport class. My guess is this is a drive/fusion interaction problem. Andrew
