(I joined the list recently so I missed the original message.)

I have an LSI 9260 with FreeBSD8.2 on a Xeon system (amd64).  It seems 
to work ok.  But it does come up griping about commands timing out 
occasionally.  See this other post of someone else who has the same 

I don't know what's going on, but except for the error, it /seems/ to be 
working.  I can still access the array.  And eventually it stops 
complaining.  I need to do more testing though before I'll really be 
satisfied that it's ok.
