I have RAID-0+1 configured. To confirm another observation of mine, do you see lots of allocated memory blocks for the controller?, e.g. imb@mail:/home/imb> sysctl -a | grep ^ata_ ata_composit: 192, 0, 69703, 117, 406336 ata_request: 200, 0, 139406, 73, 2106449 (size) (max.) (used) (avail) (requests) There appears to be a path through the ar driver which fails to free the blocks recording the requests ..
