    How are you starting cups?  The default rc.d script it installs 
    does not work without some tweaking.

    I did find that cups sends a SIGUSR1 to the init process if you ^C
    the daemon while it is starting up, which results in the machine 
    shutting down (this being a programming error by the cups people using
    getppid() to signal the 'parent' without checking whether the parent
    has detached from the child or not).  I don't know if this has anything
    to do with the crashes.

    The signal-to-init problem does not occur when I let cups startup
    manually, *BUT* I also found that cups scans all available serial ports
    during startup as well... don't ask me why.  My guess is that the crashes
    are on the same systems where you also can't run a getty on ttyd0 without
    the system crashing.
