Bug description:
My host has xfs rootfs. It runs openstack with lxc, which creates the
container root filesystems on qemu-nbd block devices with ext4fs by
default.
For probably 1 in 8 containers, when the host is working hard, I end
up with ext4 errors which in the end prevent the host from cleanly
rebooting. http://people.canonical.com/~serge/20110927_001.jpg is one
example. Here is another one:
