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

[Juerg Haefliger]

@steffel et al.

I believe there are two different problems here.

1) A generic reboot/suspend/halt issue. When powering off or suspending,
the machine doesn't fully turn off. The fan is still spinning and it can
only be revived by pulling the plug. This is what this bug is about.

2) A similarly looking problem but caused (?) by a nouveau issue as seen
in comment #18. I think this is a different issues. Please open a new
ticket for that.

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.
