The reason that both of them installed is “manjaro installs open source drivers by default” ?
Or mhwd didn’t uninstall intelligently amd-ucode for me?
I also found radeon related packages installed, and I uninstalled them with no issue.
But this time, after I uninstalled amd-ucode, the system can’t boot, the error says something like “file not found or not loaded: /@/boot/amd-ucode.img”
After a second time of “long press power button” to restart, I adjust the initrd line to boot successfully and executed:
update-grub
grub-mkconfig -o /boot/grub/grub.cfg

I had both amd-ucode and intel-ucode installed in the same OS for many years, as I would occasionally move the disk between AMD and Intel-based machines (in a removable caddy).
Having both installed hasn’t caused any issues – amd-ucode basically remains dormant when in an Intel machine, as it isn’t used; and, vice versa.
I strongly recommend not doing that if it can be avoided. Every hard reset can potentially cause damage to your system.
Instead, consider using REISUB/REISUO:

I suggest check if GRUB bootloader parameters include amd-ucode
inxi -Sa
GRUB parameters can be changed by editing /etc/default/grub and rebuilding GRUB
IF you change motherboard and/or CPUfrom amd to intel
the installed system will work in the new environment…
Make sense, but not for my laptop though.
But I could move the disk to another hardware setup, eg: a desktop, without problems, ah, got it.
