Hi!

Compiled linux kernel (git version 4.7.0-rc6+) using my own kernel
config file, enabling :

CONFIG_BTRFS_FS_RUN_SANITY_TESTS=y
CONFIG_BTRFS_DEBUG=y
CONFIG_BTRFS_ASSERT=y

and now I can't load btrfs module:

# modprobe btrfs
modprobe: ERROR: could not insert 'btrfs': Invalid argument


and in logs (and on console):

this is sparc64 sid/unstable debian:

# uname -a
Linux nvg5120 4.7.0-rc6+ #38 SMP Thu Jul 7 14:51:23 MSK 2016 sparc64 GNU/Linux

PS: using btrfs-progs from kdave repo,
git://git.kernel.org/pub/scm/linux/kernel/git/kdave/btrfs-progs.git ,
i'm able to create fs, but unable to mount:

root@nvg5120:/home/mator/btrfs-progs# ./mkfs.btrfs -f /dev/vg1/vol1
btrfs-progs v4.6.1

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.
