On kernel 4.6.2 i can load the module on quite a few machines (e6k, 
v210, v215, m4000, t5120). However, i can only create / mount raid 0,1, 
and 10 filesystems. raid 5 and 6 fails on both creation and mounting. 
Also, After creation / mounting of a raid 0/1/10 filesystem btrfs will 
eventually corrupt itself after a large amount of data has been written.

Not the same issue you are experiencing, but it's worthwhile to note.
