Public bug reported:
I've encountered the following kernel crash on a system that heavily
uses overlayfs. While not necessarily an overlayfs problem, it (adding
overlayfs) was the last major change to the system.
During the crash rsync was synchronizing non-overlayfs directory which
was bind-mounted on an overlayfs filesystem (i.e., /home under schroot).
