I am not able to access btrfs on PowerPC. I did not test all of them,
but other filesystems I tried are OK. Looking at platforms, PPC seems
to be the only BE platform widely used for Linux; there are SPARC and
MIPS but I doubt they use btrfs often.
It sounds like missing endian conversion somewhere; any idea how it can
be found without learning btrfs by heart? :)

Can you reproduce it in grub-fstest from userspace? That would let you
use gdb et al.

Unfortunately I do not have PPC userspace available ...

Forget it. It is already fixed in GIT, just that our sources missed
this patch. Sorry for the noise.
