I had an ASUS M5A99FX Pro 2.0 motherboard running Debian Trixie Linux in CLI mode on a server. The motherboard failed after a power outage. I had another motherboard of the same model running the same version of Linux, except using the KDE desktop, and with completely different peripheral cards.
I pulled the unit off the desktop and installed it into the server. Not too surprisingly, I had to clear the CMOS to get the unit to POST, which unfortunately means the BIOS settings were lost. I reset the settings to the best of my ability to remember. The unit loads the kernel, but no matter what I try, it will not start the /init. Apparently it halts just after the last kernel command concludes. There is no error… it just halts.
I have tried an earlier version of the kernel and every BIOS switch of which I can think. I have tried booting from different drives, both SSD and spinning hard drives, and both over SATA and USB.
I am loading the kernel in GRUB using:
linux /boot/vmlinuz-6.12.107+deb13-amd64 root=UUID=884a0f09-f70f-497c-9bd4-c2192c2868d6 ro earlyprintk=efi,keep log
Here is the last page of the boot:

I really think this must be a BIOS setting, but I cannot think what. I have tried changing:
OS Type: Other OS
EHCI Hand-off: Enabled
Core C6
C1E
Launch CSM: Enabled.
The BIOS refuses to let me change the CSM setting. It automatically changes it back complaining about the graphics card. The CPU is an AMD FX-8350.
