I just built a BETA4 kernel from the a checked out sources of last
night and re-enabled the debugging options.  This morning the kernel
didn't have any problems booting my system.  I'm currently building a
kernel without debugging options to see if the problem re-occurs.

I'll know if it works in about 8hrs, when I get home from work.
