vmcore.x was too big to upload to the bug tracker, so I put it here: menche.us/files/vmcore.6
Add to Summary and assign; notify nvidia maintainer as well.
What driver version was it? NVidia drivers had been recently updated (ports 374695) to address CVE-2014-8298 vulnerability, but they very likely include other fixes as well. Would you be willing to try the latest version (unless you already do so)? Similar crash was reported earlier: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=195806 Also on FreeBSD-10/amd64. Reported states issue does not occur with 331.67 driver version.
Do you still have problems with the recent updates to the NVIDIA drivers?
I have not had any more crashes since the recent nvidia driver updates.
