[Bug 585175] [NEW] kernel BUG at /build/buildd/linux-2.6.34/ubuntu/aufs/f_op.c:84!

Mon May 24 23:25:50 UTC 2010

Public bug reported:

Trivial use of aufs doesn't crash, but trying to start up an aufs
directory from schroot fails, and then the umount cannot even clean it
up.  During set up, it's /etc/schroot/setup.d/22nssdatabases that
finally triggers the issue.
