Tested with my SAS3 card and an enclosure. Relevent dmesg bits are:

Did some IO to the disks and got read/write performance at exactly the 
speeds I'd expect >170MB/s read and a little less for writing.

So this tests one the cards you have brought in. I do have some other 
12G hosts but I think they are the same chip. They would be more awkward 
to test with as they are serial console only machines that have only 
ever been tested running linux.

These disk are in an enclosure so if you want me to test hotplug stuff 
with this setup I can. Any data on the disks is entirely sacrificial at 
the moment.

One thing that surprised me was that I was testing with the USB install 
image but instead of landing in sysinst I ended up at a a login prompt 
which was unexpected. Could this be because the USB disk that was my 
root device ended up as sd23 and there is a hard coded sd0 somewhere in 
the install code?
