I'm using untouched /etc/refind-btrfs.conf

I have an Arch VM with the exact same setup minus initrd /intel-ucode.img in refind.conf and refind-btrfs works just fine on it.

Any idea? Thanks.

Yep, I don't expect two (or more) "initrd" fields to appear in the boot stanza but at most one. What you can do is this:

options  "cryptdevice=UUID=[...]:luks root=/dev/mapper/luks rootflags=subvol=@ resume=/dev/mapper/luks resume_offset=16400 quiet rw initrd=/intel-ucode.img"

That is, relocate the "initrd" field's value ("/intel-ucode.img) and put it inside the "options" field. This use case isn't really explained well (or mentioned even, it's the first time I see this) in the official rEFInd documentation and it would be quiet a bit of work to support a collection instead of a simple scalar.

You can see the exact error here:

    initrd = only(always_iterable(main_options.get(RefindOption.INITRD)))
File "/usr/lib/python3.9/site-packages/more_itertools/more.py", line 3063, in only
    raise too_long or ValueError(msg)
ValueError: Expected exactly one item in iterable, but got '/intel-ucode.img', '/initramfs-linux.img', and perhaps more.

Thank you, that did the trick!
