I am having the exact same problem in 8.10 (kubuntu fresh install) with my six disk raid 5 array. I'm using software raid, so I'm not sure if that is exactly the same. What motherboard are you using? I'm using an asus p5q and all drives are plugged into the onboard sata controller, not the onboard xpress backup ports(I believe it's an intel sata controller).
Here's the relevant bit of my /var/log/messages: Nov 5 12:49:12 serverv2 -- MARK -- Nov 5 13:09:12 serverv2 -- MARK -- Nov 5 13:29:12 serverv2 -- MARK -- Nov 5 13:49:12 serverv2 -- MARK -- Nov 5 14:09:12 serverv2 -- MARK -- Nov 5 14:29:12 serverv2 -- MARK -- Nov 5 14:49:12 serverv2 -- MARK -- Nov 5 15:09:12 serverv2 -- MARK -- Nov 5 15:29:12 serverv2 -- MARK -- Nov 5 15:49:12 serverv2 -- MARK -- Nov 5 15:50:55 serverv2 python: hp-systray(init)[6671]: warning: No hp: or hpfax: devices found in any installed CUPS queue.
