I changed my grub entry for root from:

root=LABEL=/

to

root=/dev/sda8

Now I get a spontaneous reboot.  I tried to snap a photo of it before it 
reboot, but it's blurred.  I'll try again.  Weird thing is that it says 
something about wacom driver and then a reference to reiserfs or some 
such.  I don't know what the wacom driver would have to do with 
reiserfs, but I'm not using reiserfs anyway.
