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.

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.

Thanks. -- To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html 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.
