The problem does not persist in newer versions of the driver. As such, it will be fixed once the new drivers are released. Additionally, in investigating the problem it seems that enabling the flag does NOT fix the problem. As such, there is no benefit to adding the flag in any case. Considering

Compiling the Nvidia drivers with -ffixed-x18 on affected versions is also sufficient to prevent this hang/panic: https://github.com/NVIDIA/open-gpu-kernel-modules diff --git a/src/nvidia-modeset/Makefile b/src/nvidia-modeset/Makefile index 66edbf4e..d49a3bfb 100644 --- a/src/nvidia-modeset/Makef

In trying to determine if core count had any effect on this bug, I set maxcpus to 4 and tried loading the driver on the kernel with the shadow stack enabled (aka the standard -generic config). It looks like the same root issue occurred, but this time, I got a panic with a trace that corroborates th

It looks like this is the relevant option present in the upstream stable 6.8.1 defconfig but not in the 6.8.0-31-generic config that enables the defconfig kernel to load the Nvidia driver: CONFIG_SHADOW_CALL_STACK=n I suspect that the kernel team is not going to want to disable kernel support for

This issue looks to be related to kernel configuration. Using upstream stable 6.8.1 which is what the current noble being tested is rebased on. Using 'make defconfig' the nvidia module loads successfully. But with same kernel using noble config, the nvidia module experiences the same hang as with
