After an upgrade to linux-image-3.14-1-686-pae version 3.14.12-1 this problem has gone away.
It happened every time, without fail, with these versions of linux-image-3.14: 3.14.9-1 , 3.14.7-1, 3.14.4-1 The upgrade that fixed this was part of an apt-get upgrade which updated 500+ packages and it's possible the cause was some other package that was out of date. The upgrade to the new kernel did not rebuild: /lib/modules/3.14-1-686-pae/updates/dkms/nvidia-current.ko I would recommend closing this bug now. 751334: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=751334 thanks, --jack
