Bug#869079: Kernel NULL Pointer Deference During cudaMalloc()

Package: nvidia-driver
I've only hit this bug once so far, and have been running the same code
for weeks now so it's pretty rare. Not certain but I believe this was
during a large cudaMalloc().
Don't have the hardware to replicate it on another non-Debian system
ATM, so unfortunately can't confirm if the problem is specific to Debian.
Relevant package versions:
