Hmmnn. There's no console output past the standard boot messages and the
first login prompt. The VMs in question don't really produce that much.
Deathly silence from there. I can actually connect to the console and
see the previous output but it's frozen and doesn't respond to input.

Yeah one of our clusters was 32bit until we upped it to lenny. Had to
rebuild it to amd64. Mind you I had this issue in etch too.
