I do remember seeing it, it's a big part of how I isolated that this
patch series was the issue.  To be honest I hadn't got terribly far with
the diagnosis of what the actual breakage is, it took a while to isolate
as it had been a little while since I'd rebased through onto -next and
there's no diagnostics at all from the system when it fails.

I tried applying the patch but the underlying code has changed a lot so
patch gets upset, I'll try to find time to resolve them but can't
guarantee when as things are especially hectic right now.
