I've confirmed that this issue is resolved in the latest releases of the
affected driver branches. Closing this issue.

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:

diff --git a/src/nvidia-modeset/Makefile b/src/nvidia-modeset/Makefile

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

Using 'make defconfig' the nvidia module loads successfully. But with
same kernel using noble config, the nvidia module experiences the same
hang as with
