Correction, I am seeing an error message on the console. From a "clean"
startup, it took four request for the contents of /proc/uptime before the
console displayed this:
dns2 login: Kernel panic: Segfault with no mm
As you can see, it was sitting at a login prompt during the issue. Also,
unlike previous times, the uml_mconsole command appeared to "freeze" until I
presses CTRL-C. Ideas?
