Hello, please could you try to make large (hundred of GB) ext2 volume with e2fsprogs and copy large amount of data to it? On amd64 SMP (two cores) RELENG_7_0 it should lead to unrecoverable panic or scrolling strings "ext2_new_block: bit already set for block %d". On 6.2-STABLE there is no problem with linux partitions.
