Error log from /var/log/kern.log

I am in the process of evaluating 8 port SATA/SAS PCI-E controllers for 
a storage server. 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.

Disk list:
=========
sda: 160GB Samsung SP1614C
sdb: 500GB Seagate Barracuda 7200.12  (new)
sdc: 80 GB Seagate ST380021A, attached via RockerHead 100 SATA->IDE converter
sdd: 40 GB Hitachi Travelstar 5K100 HTS541040G9SA00
sde (system drive, not in RAID): Same as sdc
