I started with a Supermicro AOC-SASLP-MV8 which runs on a Marvell 6480 host controller. - Direct storage access was fine. - RAID1 with 2 disks was fine. - A RAID6 with 4 disks disconnected all drives within a very short time directly after creation, error log attached. The disks only become accessible again after cold reboot and I had to manually disconnect 2 of them in order to be able to access them at all, since the disks were immediately disconnected again by the resync process. The disks had no errors in their logs. 3 have seen extended use without problems and one is new, but also has a long SMART selftest and some hours of use without problems. They are all different, which should rule out a controller/disk interaction issue, unless such a problem on one port can kill all four ports.
