The specific issue (the bad return from printf) was worked in LP #1879987 - it was fixed recently on initramfs-tools versions: 0.122ubuntu8.17 (Ubuntu 16.04 - Xenial) 0.130ubuntu3.11 (Ubuntu 18.04 - Bionic) 0.136ubuntu6.3 (Ubuntu 20.04 - Focal) 0.137ubuntu12 (Ubuntu 20.10 - Groovy)
I'll nominate this LP for initramfs-tools and set as Fix Released. If that's still reproducible in any way, likely there's another correlated issue, please open another LP and mention it here.
