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):
[1897399.942697] Btrfs loaded, crc32c=crc32c-generic, debug=on, assert=on

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.

The sanity tests fail at some point with EINVAL, so the module will fail
to load in turn. Looking at the test itself (__test_eb_bitmaps), it does
no make any assumptions about page size etc. so this "should work".
Taking powerpc with 64k page size for another reference where the tests
work, I'm not sure what exactly could be wrong here.

This is an endianness problem with the test. It's not showing up on
powerpc because ed9e4afdb055 ("Btrfs: self-tests: Execute page
straddling test only when nodesize < PAGE_SIZE") [1] disabled that chunk
of the test. It also fails on a big-endian MIPS QEMU system with 16K
pages. I'll send up a patch.
