I think I have a similar problem, I am on a 64bit laptop with OpenBox 
and Slim. What happens for me is if I change TTYs or even try and 
shutdown the screen turns red some times other times its just a black 
screen, but during both the computer is locked up. No output in logs and 
does cause a kernel panic. They way I have been able to work around it 
after an update gets me back to seeing red again is running this little 
script. Maybe it will help you figure a work around for yours, but 
probably not though.

sudo pacman -S --noconfirm systemd-tools dbus acpid acpi xorg-server 
xorg-server-common nvidia-lts slim nvidia xorg-xinit consolekit 
nvidia-utils xorg-server-utils polkit lib32-nvidia-utils
sudo mkinitcpio -p linux-lts
sudo mkinitcpio -p linux

After this is run and I have rebooted. I can change TTYs and shutdown 
and reboot without seeing red or black and the computer just freezing. I 
honestly can not track it down, each time I think it is caused by one 
certain thing something new in an update seems to trigger it. The 
weirdest thing to me is it does not have to be an update of any of the 
packages listed in my script to trigger the issue again. Also if I 
remove any one of those, the issue persists.

Sorry if not fully related, just figured might help spring an idea or 
something for you.
