After a few review rounds happened in a side channel, I believe the

Title:
[needs-packaging] dgx-desktop-sbsa-gwdt-loader
Status in Ubuntu:
In Progress
Bug description:
Git URL: git.launchpad.net/~antoinelassagne/+git/dgx-desktop-sbsa-gwdt-loader
Upload: https://launchpad.net/~antoinelassagne/+archive/ubuntu/cypress/+packages?field.name_filter=dgx-desktop-sbsa-gwdt-loader&field.status_filter=published&field.series_filter=
This package selectively load the sbsa_gwdt watchdog, which is
necessary with certain platforms but blacklisted by default per kernel
policy
(https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1432837/comments/6).
Without it, The Nvidia DGX Spark will reboot after 10 min of uptime,
all the time.
However blacklisted kernel modules can still be loaded with modprobe.
This is a service that takes the modalias, looks for
"NVIDIA_DGX_SPARK" into it, and modprobes the watchdog if it finds it.
