[Bug 2132001] Re: [needs-packaging] dgx-desktop-sbsa-gwdt-loader

[Antoine Lassagne]

I discussed with @paride and we discovered that there was somewhat of a
precedent. The `watchdog` package loads the watchdog module that it
needs, too:
https://git.launchpad.net/ubuntu/+source/watchdog/tree/debian/watchdog.service#n10.

I wondered if the watchdog package could be relevant for me.
Unfortunately, it seems a lot broader and having it on the installer is
surely out of the question.

Installing it on a Spark may prevent it to reboot. I haven't tested but
it sounds possible since it's working on /dev/watchdog too. But it will
also impact all other machines. Also the timing will be incorrect on
spark and will trigger a racecondition, which means I would need to
apply more or less this package on top of the other to have the action=1
parameter.

Title:
  [needs-packaging] dgx-desktop-sbsa-gwdt-loader

Status in Ubuntu:
  New

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.
