What happens if you try to tell bbswitch not to disable your nvidia card at shutdown? To accomplish this, see the "Enable card on shutdown" section in /usr/share/doc/bbswitch-dkms/README.md.gz, i.e.:

### Enable card on shutdown

Some machines do not like the card being disabled at shutdown.
Add the next initscript (`/etc/init/bbswitch.conf`) :
     description "Save power by disabling nvidia on Optimus"
     author "Lekensteyn <email address hidden>"
     start on runlevel [2345]
     stop on runlevel [016]
     pre-start exec /sbin/modprobe bbswitch load_state=0 unload_state=1
     pre-stop exec /sbin/rmmod bbswitch
