Whatever it is, it seems to be gone in Linux 4.6; I just tried
linux-image-4.6.0-rc3-amd64 from experimental and the issue is not
happening anymore.

... and is supposed to be fixed upstream AFAICT (comment #10 in the

seems to be related

Looks like something that needs to be fixed in linux. :-/

Yep, union-type=overlay.

I've been seeing something similar.  Am I right to assume that these are
union-type=overlay?  If so, this seems to be a change in the kernel.

Running linux-image-4.5.0-1-amd64, I see various failures using overlay
but rebooting into linux-image-4.4.0-1-amd64 I am again able to use
schroot/sbuild.
