After rebuilding and installing world, kernel,and the
xfce4-panel,(to synch everything) and boot the
kernel.debug kernel, I'm still able to panic the
machine at will.  Each time, got the same message
"dmesg: kernel message buffer has different magic
number"
Hwever, from the panic message, I was able to grab:

Hopefully, that's what you're looking for, if not,
tell me where / what I'm doing wrong.

Thanks,

Jimmie
