  Absolutely nothing written in any log.

  I had a look at netconsole, but this is far above my pay grade ! I 
have no idea where to start with this.

  I have never tried accessing this computer from elsewhere as there is 
no other computer I have access to.
I find it very strange that the "new" 6.12 series runs perfectly fine on
my OpenSuse Tumbleweed but crashes with a tight lockup on Debian Trixie?

The only difference is that grub is installed on the Tumbleweed 
partition not on Trixie. I was forced to do this when I discovered
the Debian mkconfig utility would not install Tumbleweed kernel in 
grub.cfg properly. Perhaps because I am running BTRFS on Tumbleweed ?
