I don't know what is the origin of this error, all I can say is that I can really
recommend anybody, especially with Thinkpads that are a bit older, to use either Debian or
Linux Mint Debian Edition. I have used either of the two on various Thinkpads over many
years and hardly experienced any Probems. I totally abandoned Ubuntu when they first
integrated Google Search and other questionable things, probably 18 years ago or so.

I created a mini video of a Lenovo x470 running Ubuntu
22.04.5🤔
I learned both laptops have different xhci controllers.
x390: > 00:14.0 USB controller: Intel Corporation Cannon Point-LP USB 3.1 xHCI
Controller (rev 30)
x470: > 00:14.0 USB controller: Intel Corporation Sunrise Point-LP USB 3.0 xHCI
Controller (rev 21)

from 22.04 to 24.04 and this is when the issue began. I have upgraded the bios from 1.75
to 1.80, followed and completed a number of suggestions but the laptop will not turn off.
Interesting enough I am testing a dual-boot x470 with the same linux distro plus windows
11. This issue does not happen on this laptop.

(the current LTS). What happens when you boot from Ubuntu live USB image, can you shutdown
it down from the command line, or from the gnome menu?
