I'm sorry, I messed up the mailing list addresses - anyways, it's a bit
centos related and the thread touches the question "why on earth does my
3ware 9550SX-LP controller work under centos and why doesn't it work
under xen?" ;-)
for the discussion thread.
BTW, has anybody an idea about this issue?
