I'm going to keep this in mind and I'll run memtester here in a bit.  I 
booted a USB stick and it ran a long time with no problem.  I took a nap 
and when I got back up, it was still running.  It may still be hardware 
but this is a good sign.  I would rather it be a bad version of gcc, bad 
kernel or something than bad hardware.  I can update those easily 
enough.  I have had 30 days of uptime on this specific kernel tho so I 
sort of doubt it is that.  Still, it could be anything.

I kind of suspect the ram tho.  When I added that, I had it to reboot 
itself.  Before that, solid as a rock.  I may just disconnect and 
reconnect everything later on too.  Just in case I pulled something 
slightly off when installing the ram.

Thanks.
