[Bug 2031352] Re: Nouveau driver crash - Ubuntu 22.04.3 LTS stuck on power-off/reboot screen

[Juerg Haefliger]

I've builtt a test kernel with the above patch:
https://kernel.ubuntu.com/~juergh/lp2031352/

Can someone give it a try, please? Note that the kernel is not signed so
you need to disable SecureBoot to be able to boot it. Install linux-
image-unsigned, linux-modules and maybe linux-modules-extra.

Bug description:
  After updating to Kernel 6.2 a few days ago, I have been experiencing
  issues with my system's shutdown and reboot functions. During these
  processes, the system becomes unresponsive and hangs on a black
  screen, which displays both the Dell and Ubuntu logos. This issue is
  inconsistent; it happens sporadically. Currently, the only workaround
  I've found to successfully shut down the system is to forcibly power
  off the machine by holding down the power button for 5 seconds.

  I've also tested a fresh installation of Ubuntu 22.04.3.
