G'day all,
The archives tell of many tales of woe regarding this chip (which matches my experience).
I've added the PCI ID for it into the ahci driver, and provided I only use one of the ports it works
(tho it's kinda slow). As per everyone elses experience, if I try and read from more than one port
at one time the whole shooting match dies thusly..
Begin with modprobe ahci as it does not seem to support hotplug, so rmmod/plug drives/modprobe

I've seen plenty of reports of this floating around. I have this board on the desk for a while
before I need to install it so I can help out testing and debugging if anyone is interested.
