In the case of a storage device that suddenly disappears, or in the
case of significant file system corruption, this can result in a huge
flood of messages being sent to the console.  This can overflow the
file system containing /var/log/messages, or if a serial console is
configured, this can slow down the system so much that a hardware
watchdog can end up triggering forcing a system reboot.
