I had this problem on my PowerBook 3400c every time I tried to boot the Linux
kernel after letting MacOS boot all the way (i.e. running BootX as an app, not
a CDEV). Using BootX as a CDEV doesn't give me this problem.

Odd. I've never gotten the kernel to boot after MacOS has loaded
fully. Anyone have any ideas?
