Version 550.76- loads successfully
Version 550.67- loads successfully
- Version 550.54.15 - crashes - which is the same version as the 550 package
that hangs. Below is the crash info. What is interesting is that in an
attempt to capture more debug into I changed optimization in utils.mk from -O2
to -O0 and the crash went away. It also doesn't happen with -O1.

In an attempt to get more debug info, I tried the open driver in github
Using https://github.com/NVIDIA/open-gpu-kernel-modules
Version 550.76- loads successfully
Version 550.67- loads successfully
Version 550.54.15 - crashes - which is the same version as the 550 package
that hangs. Below is the crash info. What is interesting is that in an
attempt to capture more debug into I changed optimization in utils.mk from -O2
to -O0 and the crash went away. It also doesn't happen with -O1.

In an attempt to get more debug info, I tried the open driver in github
Using https://github.com/NVIDIA/open-gpu-kernel-modules
Version 550.76- loads successfully
Version 550.67- loads successfully
- Version 550.54.15 - crashes - which is the same version as the 550 package
that hangs. Below is the crash info. What is interesting is that in an
attempt to capture more debug into I changed optimization in utils.mk from -O2
to -O0 and the crash went away. It also doesn't happen with -O1.
