It's an assert failure, not an oops:

XFS_DA_OP_OKNOENT is set when an operation on the
directory/attribute can be expected to get an ENOENT error.
If it is not set, then the attribute/dirent is expected to be
present in the tree, and there's something wrong if it is not.
e.g. if you are removing an attribute, it is expected to be in the
tree.
PowerPC used to get regular QA coverage but hasn't for the past
couple of years, so it probably is a relatively recent problem.
I'd suggest the first thing to do is to try older kernels to
determine if the problem is specific to newer kernels, and if so, a
git bisect is probably your best bet to finding the commit that
introduced the problem.
Cheers,
Dave.
