What is this LSI SAS2 card you have with 10+ ports? The only 10+ ports 
LSI card I see is the 84016E and it is a SAS1.

You say the driver for such card is included in the vanilla kernel at 
2.6.30? That would be very nice... I grepped the 2.6.31 kernel source 
for LSI cards but I can't find device strings such as 84016E ...

Thank you
