Warning: Auto-bootstrapping CLOS completed.

I compiled and dumped the los0 image with SBCL, and booted it with
qemu like I've done many times before, only this time I got this:

Enter..Ok.
Installing los0-GC with 63238 KB.
Break: Auto-bootstrapping CLOS.

Warning: Auto-bootstrapping CLOS completed.

Only thing I can think of that's changed is, I installed the new
version of Ubuntu recently. Any idea what might have changed or if I'm
maybe missing something?
