apport information ** Description changed:
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: [ 178.736380] JBD2: I/O error detected when updating journal superblock for nbd13-8.
