Some versions of gdb don't work well on UML. One thing that often
works is to attach to UML when it's booted, just before doing whatever
you want to debug.

How are you running UML? You normally can't ^C to get back to gdb
because the UML console has put the terminal in raw mode, so it can
see ^C, ^Z, etc and pass them along to the UML foreground process.
What I normally do is kill -INT <pid>, where pid is the lowest UML
pid.
