There is no memory protection between kernel drivers, so any driver can cause another to crash. So please disable the nvidia driver temporarily and report whether this also occurs with only the i915 driver in use. Also, the kernel log you showed includes the 'D' flag indicating that there was an earlier crash. We really need to see the log for the first crash, which won't have the 'D' flag.
