Keith,

Thanks for the update. I tested Debian 12, Fedora 41 and recently live-usb for 24.04.X and 25.04 and the same results. I did narrow the issue to the two different Intel Controllers plus kernels. In the past there would be a selection of kernels to select and I do not see this option available after a complete boot up. I am presently replying to your message on the X390. But what is surprising the testing was done on Lenovo x470, with Ubuntu 22.04.5 Pro installed and there is no issue with a complete power off. I was not able to submit a bug report to launchpad because the gpg key has yet to be  accepted even with the key being submitted to an Ubuntu Server. I am an early adopter of Linux and this is the worst I have witnessed. I am going to submit a ticket to Intel and update later.

Thanks,

Myles

I agree with Tom - I'm an old fart and prefer simple/clean.

I transitioned out of unsupported Redhat-based distros way too
late, and wasted almost a year attempting to recreate my simple
Gnome working environments with Ubuntu - very slow, very bloated,
especially on ancient T60/T61 laptops with my preferred 4x3
format screens (but never enough RAM).  I read and write
scientific papers, rarely watch videos, never play games. 

After that, I tried Mint ... still too much "video game"
behavior for me, but I can understand why many like it.

I then went to straight Debian (currently Bookworm 12 on many
machines, upgraded from Bullseye 11, one test desktop running
Trixie 13).  Still learning and porting and upgrading apps ...
OpenVPN to Wireguard, for example.

Debian is CLEAN and FAST with minimal memory footprint.  My
T60s boot in 20 seconds, and shut down in ONE SECOND.  That is
important; if the Thought Police appear, my machines can be
rebooted QUICKLY to a Windows XP partition with Solitaire on
the screen.

Regards speed; all my machines have Samsung 870 EVO solid
state drives, 1TB for the laptops, 2TB for the desktops,
and large platter drives on the backup servers.  I have
not tried 4TB or larger on the Thinkpads ... but I do have
tools to rewrite the BIOS tables if necessary, and have
done that to accommodate retrofitted 2048x1536 screens.

Properly configured, I can move the Debian SSDs between
laptops and desktops, for command line upgrade or
recovery from backups.  I keep bootable spares, in case
I meak two minnie mesdakes.

So, yes, Debian!

Keith L.
