The DMA errors are visible when RAID-1 do resync (and both SATA disks, 2TB each, are connected to the same SiL 3112 card). Maybe it is the problem why I have not noticed this problem in the past. When I write new data to the volume, I cannot see DMA errors. I first noticed trouble when RAID-1 array was degraded and I tried to do resync. It was not possible, resync process failed. Once I activated internal bitmap (mdadm -G /dev/md0 -b internal), it helped and I was able to synchronize disks, I needed several tries.
