Up, leg cramps, the wet ram ain't the only thing old.  Anyway did that, 
copied the vmlinix to /boot/vmlinuz-3.8.2+, update-grub, reboot, selected 
it, got invalid magic numbers.  So I'm back on 3.12.6.  But when I went to 
make sure that 3.8.2 worked, my script had screwed that up thinking it was 
building a real, from tarball 3.8.2.  But I have that tree untouched so it 
will re-install. Which I will start and go back to bed.

Next?

Thanks.

Cheers, Gene
