While performing a series of debian updates on the host and container, as well as container destruction/creation, the kernel spits out a stack trace indicating that the there was a hung task while it was performing writeback in zfs. If I attempt to perform a "sync" command on the host, the command will not return. Also, if I attempt to reboot the server with the reboot command, the server never reboots. A power cycle is required.
